The poll gave a very clear indication of support for accepting the the document as a MPLS Working Group document. After the poll had concluded a discussion started where several opinions were voiced, including that the document is not really needed. However after discussing the topic the wg chairs has decided to accept the draft as a working group draft, since the case where an LSP coming in over an UNI and goes directly into the MPLS based Transport Network without the PW adaptation is still valid and needs to be covered. Could the authors please re-spin the draft as: draft-ietf-mpls-tp-csf-00.txt After that the draft needs to be re-worked to clearly focus on the case described - the current document needs to be published as wg doc version -00 - immediately after that a new version should be re-spun focusing on the UNI case mentioned above and a new version (-01) has to be timely published Loa, George, Ross mpls wg co-chairs From Internet-Drafts@ietf.org Wed Feb 2 23:00:13 2011 Return-Path: X-Original-To: mpls@core3.amsl.com Delivered-To: mpls@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 2FA563A6888; Wed, 2 Feb 2011 23:00:13 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.599 X-Spam-Level: X-Spam-Status: No, score=-102.599 tagged_above=-999 required=5 tests=[AWL=0.000, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 3VOSG4+v8oQF; Wed, 2 Feb 2011 23:00:10 -0800 (PST) Received: from [127.0.0.1] (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 159D03A688B; Wed, 2 Feb 2011 23:00:02 -0800 (PST) MIME-Version: 1.0 Content-Type: Multipart/Mixed; Boundary="NextPart" From: Internet-Drafts@ietf.org To: i-d-announce@ietf.org X-Test-IDTracker: no X-IETF-IDTracker: 3.12 Message-ID: <20110203070002.2362.25467.idtracker@localhost> Date: Wed, 02 Feb 2011 23:00:02 -0800 Cc: mpls@ietf.org Subject: [mpls] I-D Action:draft-ietf-mpls-ldp-upstream-10.txt X-BeenThere: mpls@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: Multi-Protocol Label Switching WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 03 Feb 2011 07:00:13 -0000 --NextPart A New Internet-Draft is available from the on-line Internet-Drafts directories.

Since there are strong interdependencies between these document we have come to the conclusion that rather than do a number of two week consecutive last call or review we want to allocate a four week period (ending approx February 28) to review and last call a number of documents. Still a bit unclear how many. You have seen the call for early review of the Rosetta Stone and the Management Overview documents. You will later today see working group last calls for the Linear Protection and the Fault Signaling documents. We have good hope that we also will be able to include the Proactive CC and CV document in this. It is possible that we will include further documents. The reviews and last call are important, and even though we do this to able progress documents smoothly please note that we still need to take care to get good reviews.

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : Proactive Connectivity Verification, Continuity Check and Remote Defect indication for MPLS Transport Profile Author(s) : D. Allan, et al. Filename : draft-ietf-mpls-tp-cc-cv-rdi-03.txt Pages : 18 Date : 2011-02-03 Continuity Check (CC), Proactive Connectivity Verification (CV) and Remote Defect Indication (RDI) functionalities are required for MPLS- TP OAM. Continuity Check monitors the integrity of the continuity of the LSP for any loss of continuity defect. Connectivity verification monitors the integrity of the routing of the LSP between sink and source for any connectivity issues. RDI enables an End Point to report, to its associated End Point, a fault or defect condition that it detects on a PW, LSP or Section. This document specifies methods for proactive CV, CC, and RDI for MPLS-TP Label Switched Path (LSP), PWs and Sections using Bidirectional Forwarding Detection (BFD). Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC2119 [1].

Bryant Filename : draft-ietf-mpls-loss-delay-01.txt Pages : 43 Date : 2011-02-04 Many service provider service level agreements (SLAs) depend on the ability to measure and monitor performance metrics for packet loss and one-way and two-way delay, as well as related metrics such as delay variation and channel throughput. This measurement capability also provides operators with greater visibility into the performance characteristics of their networks, thereby facilitating planning, troubleshooting, and evaluation. This document specifies protocol mechanisms to enable the efficient and accurate measurement of these performance metrics in MPLS networks.

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : A Packet Loss and Delay Measurement Profile for MPLS-based Transport Networks Author(s) : D. Frost, S. Bryant Filename : draft-ietf-mpls-tp-loss-delay-profile-02.txt Pages : 5 Date : 2011-02-04 Procedures and protocol mechanisms to enable the efficient and accurate measurement of packet loss, delay, and throughput in MPLS networks are defined in RFC XXXX. The MPLS Transport Profile (MPLS-TP) is the set of MPLS protocol functions applicable to the construction and operation of packet- switched transport networks. This document describes a profile of the general MPLS loss, delay, and throughput measurement techniques that suffices to meet the specific requirements of MPLS-TP. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunication Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge (PWE3) architectures to support the capabilities and functionalities of a packet transport network as defined by the ITU-T.

The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://www.ietf.org/iesg/directorate/routing.html Document: https://datatracker.ietf.org/documents/LIAISON/file1155.pdf Reviewer: David Sinicrope Review Date: 31 January 2011 IETF LC End Date: N/A Intended Status: N/A *Summary and General Comments* In general the document should be progressed pending satisfactory response to the comments below. The document eliminates Penultimate Hop Popping in several places while saying it is an option in Annex A. I believe Penultimate Hop Popping is allowed, although as Annex A points out, it is not the preferred mode of operation. Given this the text must not mandate that it cannot be used. It would be helpful to the reader if its use was addressed in the modeling. *Major Comments* - Summary, Paragraph 2, 2nd sentence - "In the event of a difference between this ITU-T Recommendation and any of the normatively referenced IETF RFCs, the RFCs will take precedence." The RFCs should take precedence in all cases. Change the text to read: "In the event of a difference between this ITU-T Recommendation and any of the referenced IETF RFCs, the RFCs take precedence." - Section 10 MPLS-TP DiffServ Architecture, paragraph 3 states: "The setting of the traffic class (TC) field is as defined in [IETF RFC 3270] and [IETF RFC 5462] for the short-pipe and uniform models with no Penultimate Hop Popping (PHP)." However Annex A allows PHP. Please change the text to "The setting of the traffic class (TC) field is as defined in [IETF RFC 3270] and [IETF RFC 5462] for the short-pipe and uniform models." - Section 10 MPLS-TP DiffServ Architecture, paragraph 5 states: "In order to support short-pipe and uniform tunnelling modes, as defined in [IETF RFC 3270], the Server/MT_A_So function is configured, on individual MT_CP basis, to encode the TC field based on one of the following QoS Encoding Modes: - QoS Encoding Mode A where the TC field is encoded according to the outgoing PHB information; - QoS Encoding Mode B where the TC field is encoded with any value (representing non-meaningful Diff-Serv information)." The TC field must never be used for any purposed other than encoding traffic class information. Please remove Mode B and add the following text "The TC field is encoded and used for QoS indications or, if not used, is silently ignored." - Section 10.1.1 Short Pipe Model, 1st sentence: "The transport processing functions and processes for the short-pipe model (without penultimate hop popping) are described in Figure 10-1. Remove "(without penultimate hop popping)" from the sentence per the inconsistency with Annex A highlighted in the comment above. Please add a second figure showing the PHP case for consistency with Annex A. - Section 10.1.2 Uniform Model, 1st sentence: "The transport processing functions and processes for the Uniform model (without penultimate hop popping) are described in Figure 10-2. Remove "(without penultimate hop popping)" from the sentence per the inconsistency with Annex A highlighted in the comment above. Please add a second figure showing the PHP case for consistency with Annex A. *Minor Comments* - Section 1 Scope, paragraph 6 - "MPLS-TP is a connection-oriented packet-switched transport layer network technology that uses MPLS-TP LSPs and PWs" Should read "MPLS-TP is a connection-oriented packet-switched transport layer network technology that uses PWs and MPLS-TP LSPs per the definition in section 1.3.4 of RFC 5921]" There is no definition of an MPLS-TP PW, and the text should be clear on the definition of an MPLS-TP LSP. - Section 1 Scope, paragraph 6 - "... allows consistent operations with other transport technologies" should be "... allows operation consistent with other transport technologies." - Section 2 References - What is the reason for moving the Survivability framework draft reference (top of page 8) to the Bibliography (bottom of page 46)? It is still listed in the "Scope" clause (1), Functional architecture clause (6), MPLS-TP MEG clause (8.1.3), MPLS-TP survivability techniques clause (9) and Security aspects clause (12). Since the referenced document has now been approved for publication as an RFC, it would make sense to move this reference back to the References section from the Bibliography. - Section 6.1 MPLS-TP Network Layered Structure - No definition of "the MPLS-TP network architecture". Please provide a reference to the definition of the architecture. Reference section 1.3 of RFC 5921. - Section 6.1 MPLS-TP Network Layered Structure - "PWs in MPLS-TP can only be carried over MPLS-TP LSPs." should be "While PWs can only be carried over MPLS LSPs, this document only addresses the case where PWs are carried over MPLS-TP LSPs." The structure as defined is overly restrictive. - Section 6.1 MPLS-TP Network Layered Structure - "The MPLS architecture does not have a minimum packet length. When MPLS packets are transmitted over a non-MPLS-TP server layer with a minimum frame size, the Server/MPLS-TP adaptation function will pad these packets to the minimum frame size of that non-MPLS-TP server layer. This padding is removed at the adaptation sink of the non-MPLS client. The mechanisms for mapping clients over MPLS-TP provide appropriate information (e.g. the length field in the Control Word) to remove the padding at that MPLS-TP/Client adaptation sink function." This paragraph discusses MPLS client adaptation to non-MPLS-TP server layers. Please explain the relevance to MPLS-TP Network Layered Structure. - Figure 6-5 see comment on Section 1 Scope paragraph 6. - Section 6.1.2/6.2.3.1 MPLS Trail Termination section 6.1.2 states "the assignment of the S and TTL fields in the LSP or PW Label Stack Entry (LSE) of a G-ACh packet is defined in the MPLS-TP Trail Termination (MT_TT) function" however, nothing is mentioned about the S bit in section 6.2.3.1. - Section 6.1.2 MPLS-TP Characteristic Information - States "The MT_CI traffic units (MT_CI_D) are accompanied by the MT_CI_iPHB, MT_CI_oPHB, MT_CI_SSF and optional MT_CI_APS signals." There is no definition of MT_CI_APS that I can find in G.8110 or other ITU-T documents. Please add specific normative references to the definition of MT_CI_APS. - Section 6.4 MPLS-TP Network Topology Last sentence before section 6.4.1 "The control plane aspects are out of the scope of this Recommendation." should read "The control plane aspects are not prohibited, but are outside the scope of this Recommendation." Control plane function is part of the MPLS-TP requirements. - Section 6.4.1 Unidirectional and bidirectional connections and trails - Need to clarify this text. It sounds like unidirectional connections in the server layer cannot be combined to carry bidirectional MPLS-TP connections. If this is the intention of the text, it should be brought out more strongly. However, it seems like an unnecessary restriction. - Figure 6-9 - Point to multipoint MPLS-TP subnetwork connection - The previous paragraph states the traffic is broadcast from the root to the leaves. Yet in this figure there are some leaves not receiving the broadcast. Is the traffic multicast instead of broadcast and if so what is the criteria of the multicast? Also if the traffic is sent from root to leaf, what are the horizontal inter leaf communications in the figure? The horizontal lines are labeled "MPLS-TP LC" which may indicate to the reader the exit from the subnetwork, however it is unclear whether they indicate this or communication paths. - Section 6.5 MPLS-TP Label Behavior, 1st sentence - It would be good to provide some specifics here. This sentence references hundreds of pages of documentation not all of which is relevant to label allocation and behavior. - Section 6.5.2 last paragraph before 6.5.3 states "When a request is made to a label manager, a particular label value can be suggested. However there is no guarantee that the suggested label value would be allocated." How is a particular label suggested? If done via management this function is outside the scope of the recommendation. If done via the control plane, this is also outside the scope of the recommendation. In either case, this is an internal function and should be removed from the text. - Section 7 Server/Client Associations states "- MT/client adaptation, where the client is not MPLS-TP. - MT/MT adaptation, for supporting hierarchical MPLS-TP LSPs." - See comment on section 1 regarding "MPLS-TP LSPs". It is not clear whether MPLS is included or excluded as a client in the context of MPLS-TP LSPs. Please clarify. - Section 7.1.1 MT/ETH adaptation, 3rd paragraph, 1st bullet - The text says "Insert the CW word..." Insert between what? It isn't clear what the starting data is for these steps. - Section 7.1.1 MT/ETH adaptation, 3rd paragraph, after 1st bullet - Add "If required, the CW is inserted between and . The sequence number processing may be performed." Without this text it is inconsistent with the 4th paragraph last bullet. and should indicate the points of insertion that will be clarified by the comment above. - Section 7.2 MT/MT adaptation, 3rd paragraph, 3rd bullet - What protocol is the CI_APS based? Please provide a specific normative reference for the definition and details of CI_APS. - Section 7.3 Server/MT adaptation states: "Further definition of the processes to adapt MPLS-TP to server layers is outside the scope of this Recommendation and will be described in [b-ITU-T G.8121]." Shouldn't this say "is described in [b-ITU-T G.8121]"? - Section 8 MPLS-TP OAM Architecture - States "The MPLS-TP OAM mechanisms and implementation are outside the scope of this Recommendation." Change this text to "The MPLS-TP OAM mechanisms are defined in the IETF RFCs and are outside the scope of this Recommendation." *Editorial Comments* - Section 6.2.1.3 MPLS-TP Link uses the access group term before it is defined in 6.2.1.4. It is recommended to swap these sections in the document order. - Figure 6-8 - The arrow should point to MT LC vs. TM LC. - Section 10.1 seems to be missing. The text jumps from section 10 to 10.1.1.

Hi = Experts,

 

I = have few questions and clarifications on MPLS-TP LSP labeling = before I speed up into MPLS-TP world.

 

1. Is MPLS-TP LSP uses special label value = allocated static/dynamically. ?

 

2. why MPLS-TP LSP needs to be bidirectional and = does each LSR/LER need to bind the bi-directional LSP's = association.?

 

3. My assumption is that MPLS-TP lsp is nothing = but normal LSP created statically/dynamically used to carry data and = in-band channel information over it.?

 

4. My assumption is that = each Pseudowire data circuit will have 1:1 = MPLS-TP Pseudowire for in-band channel communication to operate OAM = function on Pseudowire.?

 

5. Is bi-directional LSP symmeric  or = not?

 

6. If it is Asymmetric, if one direction of the = MPLS-TP lsp goes down, do we need to make other direction of the paired = LSP to  make it down.?

 

Please clarify my = question.

 

Many thanks in advance.

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : mLDP based in-band signaling for Point-to-Multipoint and Multipoint-to- Multipoint Label Switched Paths Author(s) : I. Wijnands, et al. Filename : draft-ietf-mpls-mldp-in-band-signaling-03.txt Pages : 13 Date : 2011-02-08 Suppose an IP multicast tree, constructed by Protocol Independent Multicast (PIM), needs to pass through an MPLS domain in which Multipoint LDP (mLDP) Point-to-Multipoint and/or Multipoint-to- Multipoint Labels Switched Paths (LSPs) can be created. The part of the IP multicast tree that traverses the MPLS domain can be instantiated as a multipoint LSP. When a PIM Join message is received at the border of the MPLS domain, information from that message is encoded into mLDP messages. When the mLDP messages are received at the border of the next IP domain, the encoded information is used to generate PIM messages that can be sent through the IP domain. The result is an IP multicast tree consisting of a set of IP multicast sub-trees that are spliced together with a multipoint LSP.

I have some issues with this draft:
There had been a lot of discussions on email list on what should Initiator (querier) do when not receiving a response from far end.
 
 
When initiating an LM operation, the far end may require a period of time to become ready for the requested measurement operation or the far end may not be able to support the requested measurement. Under those circumstances, LM queries MAY simply be discarded, and the querier expecting a response SHOULD be prepared for this situation. Alternatively, the receiver MAY respond, possibly in a rate-limited manner, to queries received during this period with an appropriate notification code.  The querier should abort the measurement after not receiving any positive feedback when a specified timer expires. 
 
 
 
Section 3.5.3: It stated:
When a query is received with a Session Query Interval that is too low for the receiver to support, the receiver SHOULD include this object when it generates an error response.
 
Question:
Which error code should be used? Is it 0x18:Error - Unsupported Query Interval? If Yes, should add this to the sentence.
 
What if the Querier indicates "0x2: No Response Requested"?
 
Section 4.1.5:
  • Should allow the Loss measurement to be calculated somewhere else, in case the initiator (querier) doesn't have the capacity to do the calculation.
  • Should add a description that measurement is to be stopped when far end not respond anymore.

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : MPLS On-demand Connectivity Verification and Route Tracing Author(s) : N. Bahadur, et al. Filename : draft-ietf-mpls-tp-on-demand-cv-02.txt Pages : 17 Date : 2011-02-09 LSP-Ping is an existing and widely deployed OAM mechanism for MPLS LSPs. This document describes extensions to LSP-Ping so that LSP- Ping can be used for On-demand Connectivity Verification of MPLS-TP LSPs.

There is a "be" lost between "can" and "only". 2.Section 3.5.2 "1. BFD control packets are received with an unexpected encapsulation (mis-connectivity defect), these include: - a PW receiving a packet with a GAL", Since GAL can be used for PW(http://tools.ietf.org/html/draft-ietf-pwe3-mpls-tp-gal-in-pw-00), this should not be a defect. Suggest to remove it. 3 Section 3.5.2 " 4. Receipt of an expected session discriminator with an unexpected label (mis-connectivity defect).", For a receiver, how does it know that the session discriminator is valid but the label is invalid? IMHO, this defect is just another description of defect 3 . Suggest to remove it. 4.Section 3.5.4.2 " Exit from a misconfiguration defect occurs when two consecutive CC or CV frames have been received with the expected M bit setting." IMHO, this sentence is little bit vague, and since this draft only defines for P2P LSP, why not just say "...with M bit clear." 5. Section 3.5.4.3 "Exit from a mis-connectivity defect state occurs when no CV messages have been received with an incorrect source MEP-ID for a period of 3.5 seconds.", since there are several defects listed in Section 3.5.2 and this is only one condition for exiting from a mis-connectivity defect state. How about "Exit from a mis-connectivity defect state occurs when no CV messages with mis-connectivity defects have been received for a period of 3.5 seconds " 6. Section 3.5.5 In Figure 5, seems that it is lack of "AIS-LDI, LKR" inputs for DOWN state.

In the section 5.1, the third paragraph, it said "The message is then sent. The message MUST be refreshed two more times at an interval of one second. Further refreshes are sent according to the value of the refresh timer." I don't know why the refreshing massage must be first sent two more times in one second and then sent as the refresh timer interval. Is it ok if the refreshing massage is sent only according to the value of the refresh timer? If it is not, what problem may be introduced? Hope authors could explain it for me. In addition, figure 2 is about the fault management massage format, so I think naming the figure" MPLS-TP fault Management Message Format " other than" MPLS-TP OAM Message Format " is more suitable.

We therefore request that the changes and comments identified below are addressed and that we are given a further opportunity to review this draft recommendation before the document is advanced through the ITU-T publications process. The document eliminates Penultimate Hop Popping in several places while saying it is an option in Annex A. I believe Penultimate Hop Popping is allowed, although as Annex A points out, it is not the preferred mode of operation. Given this the text must not mandate that it cannot be used. It would be helpful to the reader if its use was addressed in the modeling. *Major Comments* - Summary, Paragraph 2, 2nd sentence - "In the event of a difference between this ITU-T Recommendation and any of the normatively referenced IETF RFCs, the RFCs will take precedence." The RFCs should take precedence in all cases. Change the text to read: "In the event of a difference between this ITU-T Recommendation and any of the referenced IETF RFCs, the RFCs take precedence." - Section 10 MPLS-TP DiffServ Architecture, paragraph 3 states: "The setting of the traffic class (TC) field is as defined in [IETF RFC 3270] and [IETF RFC 5462] for the short-pipe and uniform models with no Penultimate Hop Popping (PHP)." However Annex A allows PHP. Please change the text to "The setting of the traffic class (TC) field is as defined in [IETF RFC 3270] and [IETF RFC 5462] for the short-pipe and uniform models." - Section 10 MPLS-TP DiffServ Architecture, paragraph 5 states: "In order to support short-pipe and uniform tunnelling modes, as defined in [IETF RFC 3270], the Server/MT_A_So function is configured, on individual MT_CP basis, to encode the TC field based on one of the following QoS Encoding Modes: - QoS Encoding Mode A where the TC field is encoded according to the outgoing PHB information; - QoS Encoding Mode B where the TC field is encoded with any value (representing non-meaningful Diff-Serv information)." The TC field must never be used for any purposed other than encoding traffic class information. Please remove Mode B and add the following text "The TC field is encoded and used for QoS indications or, if not used, is silently ignored." - Section 10.1.1 Short Pipe Model, 1st sentence: "The transport processing functions and processes for the short-pipe model (without penultimate hop popping) are described in Figure 10-1. Remove "(without penultimate hop popping)" from the sentence per the inconsistency with Annex A highlighted in the comment above. Please add a second figure showing the PHP case for consistency with Annex A. - Section 10.1.2 Uniform Model, 1st sentence: "The transport processing functions and processes for the Uniform model (without penultimate hop popping) are described in Figure 10-2. Remove "(without penultimate hop popping)" from the sentence per the inconsistency with Annex A highlighted in the comment above. Please add a second figure showing the PHP case for consistency with Annex A. *Minor Comments* - Section 1 Scope, paragraph 6 - "MPLS-TP is a connection-oriented packet-switched transport layer network technology that uses MPLS-TP LSPs and PWs" Should read "MPLS-TP is a connection-oriented packet-switched transport layer network technology that uses PWs and MPLS-TP LSPs per the definition in section 1.3.4 of RFC 5921]" There is no definition of an MPLS-TP PW, and the text should be clear on the definition of an MPLS-TP LSP. - Section 1 Scope, paragraph 6 - "... allows consistent operations with other transport technologies" should be "... allows operation consistent with other transport technologies." - Section 2 References - What is the reason for moving the Survivability framework draft reference (top of page 8) to the Bibliography (bottom of page 46)? It is still listed in the "Scope" clause (1), Functional architecture clause (6), MPLS-TP MEG clause (8.1.3), MPLS-TP survivability techniques clause (9) and Security aspects clause (12). Since the referenced document has now been approved for publication as an RFC, it would make sense to move this reference back to the References section from the Bibliography. - Section 6.1 MPLS-TP Network Layered Structure - No definition of "the MPLS-TP network architecture". Please provide a reference to the definition of the architecture. Reference section 1.3 of RFC 5921. - Section 6.1 MPLS-TP Network Layered Structure - "PWs in MPLS-TP can only be carried over MPLS-TP LSPs." should be "While PWs can only be carried over MPLS LSPs, this document only addresses the case where PWs are carried over MPLS-TP LSPs." The structure as defined is overly restrictive. - Section 6.1 MPLS-TP Network Layered Structure - "The MPLS architecture does not have a minimum packet length. When MPLS packets are transmitted over a non-MPLS-TP server layer with a minimum frame size, the Server/MPLS-TP adaptation function will pad these packets to the minimum frame size of that non-MPLS-TP server layer. This padding is removed at the adaptation sink of the non-MPLS client. The mechanisms for mapping clients over MPLS-TP provide appropriate information (e.g. the length field in the Control Word) to remove the padding at that MPLS-TP/Client adaptation sink function." This paragraph discusses MPLS client adaptation to non-MPLS-TP server layers. Please explain the relevance to MPLS-TP Network Layered Structure. - Figure 6-5 see comment on Section 1 Scope paragraph 6. - Section 6.1.2/6.2.3.1 MPLS Trail Termination section 6.1.2 states "the assignment of the S and TTL fields in the LSP or PW Label Stack Entry (LSE) of a G-ACh packet is defined in the MPLS-TP Trail Termination (MT_TT) function" however, nothing is mentioned about the S bit in section 6.2.3.1. - Section 6.1.2 MPLS-TP Characteristic Information - States "The MT_CI traffic units (MT_CI_D) are accompanied by the MT_CI_iPHB, MT_CI_oPHB, MT_CI_SSF and optional MT_CI_APS signals." There is no definition of MT_CI_APS that I can find in G.8110 or other ITU-T documents. Please add specific normative references to the definition of MT_CI_APS. - Section 6.4 MPLS-TP Network Topology Last sentence before section 6.4.1 "The control plane aspects are out of the scope of this Recommendation." should read "The control plane aspects are not prohibited, but are outside the scope of this Recommendation." Control plane function is part of the MPLS-TP requirements. - Section 6.4.1 Unidirectional and bidirectional connections and trails - Need to clarify this text. It sounds like unidirectional connections in the server layer cannot be combined to carry bidirectional MPLS-TP connections. If this is the intention of the text, it should be brought out more strongly. However, it seems like an unnecessary restriction. - Figure 6-9 - Point to multipoint MPLS-TP subnetwork connection - The previous paragraph states the traffic is broadcast from the root to the leaves. Yet in this figure there are some leaves not receiving the broadcast. Is the traffic multicast instead of broadcast and if so what is the criteria of the multicast? Also if the traffic is sent from root to leaf, what are the horizontal inter leaf communications in the figure? The horizontal lines are labeled "MPLS-TP LC" which may indicate to the reader the exit from the subnetwork, however it is unclear whether they indicate this or communication paths. - Section 6.5 MPLS-TP Label Behavior, 1st sentence - It would be good to provide some specifics here. This sentence references hundreds of pages of documentation not all of which is relevant to label allocation and behavior. - Section 6.5.2 last paragraph before 6.5.3 states "When a request is made to a label manager, a particular label value can be suggested. However there is no guarantee that the suggested label value would be allocated." How is a particular label suggested? If done via management this function is outside the scope of the recommendation. If done via the control plane, this is also outside the scope of the recommendation. In either case, this is an internal function and should be removed from the text. - Section 7 Server/Client Associations states "- MT/client adaptation, where the client is not MPLS-TP. - MT/MT adaptation, for supporting hierarchical MPLS-TP LSPs." - See comment on section 1 regarding "MPLS-TP LSPs". It is not clear whether MPLS is included or excluded as a client in the context of MPLS-TP LSPs. Please clarify. - Section 7.1.1 MT/ETH adaptation, 3rd paragraph, 1st bullet - The text says "Insert the CW word..." Insert between what? It isn't clear what the starting data is for these steps. - Section 7.1.1 MT/ETH adaptation, 3rd paragraph, after 1st bullet - Add "If required, the CW is inserted between and . The sequence number processing may be performed." Without this text it is inconsistent with the 4th paragraph last bullet. and should indicate the points of insertion that will be clarified by the comment above. - Section 7.2 MT/MT adaptation, 3rd paragraph, 3rd bullet - What protocol is the CI_APS based? Please provide a specific normative reference for the definition and details of CI_APS. - Section 7.3 Server/MT adaptation states: "Further definition of the processes to adapt MPLS-TP to server layers is outside the scope of this Recommendation and will be described in [b-ITU-T G.8121]." Shouldn't this say "is described in [b-ITU-T G.8121]"? - Section 8 MPLS-TP OAM Architecture - States "The MPLS-TP OAM mechanisms and implementation are outside the scope of this Recommendation." Change this text to "The MPLS-TP OAM mechanisms are defined in the IETF RFCs and are outside the scope of this Recommendation." *Editorial Comments* - Section 6.2.1.3 MPLS-TP Link uses the access group term before it is defined in 6.2.1.4. It is recommended to swap these sections in the document order. - Figure 6-8 - The arrow should point to MT LC vs. TM LC. - Section 10.1 seems to be missing. The text jumps from section 10 to 10.1.1.

Please may I refer you to our earlier response of 15th January 2011 entitled "Response to Updated draft Recommendation G.8121 [Ref 042.02]" Additionally, since the text of draft Recommendation for G.8121 is based on an MPLS-TP OAM protocol not designed within the IETF Standards Process this is a breach of the SG15 agreement with the IETF as published in "Report of the first meeting of Working Party 3/15 Transport network structures (2009-2012)" (Geneva, 1 12 December 2008) which can be found at http://www.itu.int/md/T09-SG15-R-0004/en. As a consequence the MPLS WG has not been asked to review this Draft Recommendation by the IETF management. When the ITU-T SG15 liaises a draft Recommendation written in accordance with the above agreement, IETF management will ask the MPLS WG to perform an in depth review. We look forward to receiving your next draft. Please can we take this opportunity state that the IETF is committed to developing the MPLS-TP solution as described in the Joint Working Team Recommendations and meeting the jointly agreed MPLS-TP requirements documented in RFC5654.

In the section 5.1, the third paragraph, it said "The message is then sent. The message MUST be refreshed two more times at an interval of one second. Further refreshes are sent according to the value of the refresh timer." I don't know why the refreshing massage must be first sent two more times in one second and then sent as the refresh timer interval. Is it ok if the refreshing massage is sent only according to the value of the refresh timer? If it is not, what problem may be introduced? Hope authors could explain it for me. In addition, figure 2 is about the fault management massage format, so I think naming the figure" MPLS-TP fault Management Message Format " other than" MPLS-TP OAM Message Format " is more suitable.

In section 1.2, it says: " The basic protocol is designed for use in conjunction with the 1:1 protection architecture (for both unidirectional and bidirectional protection) and for 1+1 protection of a bidirectional path (for both unidirectional and bidirectional protection switching). " Would you please explain why coordination is needed for unidirectional protection switching in 1+1 protection of a bidirectional path? Because section 4.7.2 of tp-survive-fwk says: "In 1+1 unidirectional protection switching there is no need to coordinate the protection state between the protection controllers at both ends of the protection domain." I guess you mean 1+1 protection may need coordination to keep traffic on co-routed paths, but that would be bidirectional protection switching. Hope this could be made clearer in this draft. 2. Section 2.1, Acronyms The full name of "LER" should be "Label Edge Router" "PST" is an old term replaced by SPME (Sub-Path Maintenance Entity), but neither is used in the following sections, so it may be removed from acronyms. 3. In Section 3, there is only one level-2 subsection (3.1), so what about promote the level-3 subtitles (3.1.1, 3.1.2, ...) to level-2, and level-4 (3.1.6.1) to level-3? 4. Section 4, 3rd paragraph, s/single-phase/single-phased, to be consistent with 2nd paragraph. 5. Section 4.1, 4th paragraph, " In the event a signal fail condition is detected on the protection path, the received PSC specific information should be evaluated." The statement is vague. What would be the state and action when a signal fail is detected on the protection path? Would you please elaborate on this point? 6. Section 4.2.2, 4th paragraph, " The Fpath field SHALL identify the path that is reporting the failure condition (i.e. if protection path then Fpath is set to 0...". Since PSC message are only transmitted on protection path, if protection path has signal fail, the PSC message may not be able to be sent out to far-end. 7. Section 4.3.2, there is signal degrade on working path as input, but no signal degrade on protection path. 8. Section 4.3.3, I go through this part fast, a general question is: are the PSC operations for 4 different protection types identical ? In this section there is no description about operation of each specific protection type, but to my understanding, there may be different operations, e.g., for bidirectional 1:1 protection, the end point may need to switch the sink selector and transmitting bridge simultaneously according to some input, but for unidirectional 1:1 the end point may only need to switch the transmitting bridge OR the sink selector. And the PSC message sent may also be different for different protection types. (Please correct me if there is anything wrong with this thought).

Simplify it will be more smart. 2.section 4.1.2, the first sentence" This TLV carries the Interface Identifier as defined ......", "the Interface Identifier" should be "the Global Identifier". right? 3. section 5.3, there are two "that" in the first sentence, one is redundancy.

In the section 5.1, the third paragraph, it said "The message is then sent. The message MUST be refreshed two more times at an interval of one second. Further refreshes are sent according to the value of the refresh timer." I don't know why the refreshing massage must be first sent two more times in one second and then sent as the refresh timer interval. Is it ok if the refreshing massage is sent only according to the value of the refresh timer? If it is not, what problem may be introduced? Hope authors could explain it for me. In addition, figure 2 is about the fault management massage format, so I think naming the figure" MPLS-TP fault Management Message Format " other than" MPLS-TP OAM Message Format " is more suitable.

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : Operations, Administration and Maintenance Framework for MPLS-based Transport Networks Author(s) : D. Allan, et al. Filename : draft-ietf-mpls-tp-oam-framework-11.txt Pages : 65 Date : 2011-02-11 The Transport Profile of Multi-Protocol Label Switching (MPLS-TP) is a packet-based transport technology based on the MPLS Traffic Engineering (MPLS-TE) and Pseudowire (PW) data plane architectures. This document describes a framework to support a comprehensive set of Operations, Administration and Maintenance (OAM) procedures that fulfill the MPLS-TP OAM requirements for fault, performance and protection-switching management and that do not rely on the presence of a control plane. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunications Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and PWE3 architectures to support the capabilities and functionalities of a packet transport network as defined by the ITU-T.

We are concerned that this draft recommendation has been aligned with draft-bhh-mpls-tp-oam-y1731-06, since this is not an MPLS OAM protocol deigned within the IETF Standards Process. In particular we note that document only specifies the ICC-based MEG_ID and is therefore missing the IP based identifiers specified in draft-ietf-mpls-tp-identifiers-03. The MEP_ID is also not aligned with the MEP_ID defined in the above IETF draft. We are also concerned that this document defines an MPLS-TP MEL since a MEL is not a construct supported in MPLS-TP. We look forward to receiving a revised version of the draft Recommendation that is aligned with the jointly agreed MPLS-TP design. Please can we take this opportunity state that the IETF is committed to developing the MPLS-TP solution as described in the Joint Working Team Recommendations and meeting the jointly agreed MPLS-TP requirements documented in RFC5654.

Hi Ice,
From the technical point of view, the leaf node (will never be Bud node, if ensure) can enable PHP if LSP carries IP multicast traffic (application described in draft-ietf-mpls-mldp-in-band-signaling-03), right? The bud node should always disable the PHP. But the problem is that one leaf node may become a bud node in future. Then what is the PHP behavior for draft-ietf-mpls-mldp-in-band-signaling-03?
draft-ietf-mpls-ldp-p2mp does not describe the PHP behavior for node, does that mean the application binding P2MP/MP2MP LSP should address the PHP behavior?

Thanks

I've still not seen an mentioning of benefits, eg: performance downside is IMHO a historical argument. With inband signaling, i also have the most simple example of why it can break things. If the downstream PE wants to fail over for the same (S,G) between two headend PE, then it is that last-hop label that provides the ability to drop the currently unwanted version of the (S,G) flow during switchover. The same would be true for any other switchover cases on the tailend PE between different LSPs. Or just the generic considerations: I only want labelled multicast packet on my core, that way i can much better distinguish them from my native multicast packets on the CE side. I want mLDP to stay simple, and consistently doing label binding all the way from headend LSR to tailend LSR makes the last hop not a special case where i need to spend always level of design considerations.

Hi Toerless,
It is not my intention to allow PHP for mLDP, and I agree with you to disable PHP for mLDP. Since PHP is the default function in many current MPLS implementations, it is necessary for the mLDP in-band signaling draft to explicitly describe whether PHP should be always disabled or enabled, so as to avoid misunderstanding.

For unidirectional measurements this can be accomplished simply by sending the out-of-band response to the post-processing system identified by the return address TLV. For bidirectional measurements the querier can forward the final measurement message using the same out-of-band mechanism used by the responder to = the address of the desired post-processing system. Some port-processing systems may have the ability to store measurement data for an extended measurement period and produce a variety of useful statistics from the measurement data. Use of an off-line post-processing system also allows = the measurement function at the querier to be completely stateless. The = option to support off-line post-processing should be included (and should = require only a small amount of additional text to describe). 2) In section 1 the work =93packet=94 should be deleted from the bullet = =93The LM protocol supports both 32-bit and 64-bit packet counters.=94 since octet counters are also supported. 3) In section 2.1 the received packet count is described as not = including the LM packet itself. Unless the LM messages are excluded from the = counting altogether, it may be easier to include the LM packet in the count as it must be received (and likely would be counted) before it is recognized = as andLM packet and further processing occurs. It may be easier to add one = to the count when the LM message is sent than to subtract one when the LM message is received. It could also be specified that the sending count = does not include the LM packet and the receiving count does and the = correction can be handled I the post-processing calculations (keeping the LM query/response functions as simple as possible). 4) In 2.2 the phrase "measurement of the throughput sustained over the channel during the interval" would be better without "sustained" which = tends to suggest a constant rate. 5) In 2.2 the statement "This metric can be called the delivered throughput." should be expanded since the values recorded allow = calculation of both offered throughput and delivered throughput. 6) In 2.2 the phrase "As for loss measurement," should be deleted since = this section is about throughput measurement (and the particular sentence = appears to be as well). 7) It is noted that due to the TC of the measurement messages they may = be reordered with respect to other packets. It should be further noted somewhere that, while this can affect individual measurements in the = direct measurement method, the packet loss rate (derivative of packet loss measurement) can still be accurately determined over time. Some places where this might be noted are in 2.7.2, 2.7.3, and/or 2.7.6. 8) Presumably the editor's note in 2.7.5 is no longer needed. 9) In 3.1 there should be a notification value (0x5?) for the case that = the egress measurement resource is preempted or released by an administrator (indicating the measurement session should end). 10) In 3.1 the case of "Unsupported Version" is indicated as an error. = It may be better to make this a notification so that the querier can decide whether or not the earlier version responder can nevertheless provide = useful data. There may be cases in which the responder does not have to be upgraded to make beneficial use of additional information (e.g. in TLVs) sent by the querier and returned (without being understood) in the = response message. If this is desirable, then 4.1.4 should indicate that optional TLVs are copied in the response if they are not understood. 11) In 3.1 the control code 0x15 mentions "Destination Node Identifier" = -- is this the Destination Address (TLV 129)? If not, to what does it = refer? 12) In 3.1 to what does the "channel identifier supplied in the query" = refer in the description of control code 0x16? 13) In 3.2 the description of the Flags field is a bit confused. It = refers to similarity with 3.1 and the X flag (which is in the DFlags field, not = in the Flags field). 14) In 3.5.3, since it is likely that the minimum supported LM interval = will vary for different endpoints and that useful measurements are not necessarily dependent on the interval chosen, it would be more useful = for the suggested process to be the following: The querier need not send a Session Query Interval TLV in the initial LM query, the responder SHOULD send a Session Query Interval in the initial responses (indicating the minimum supported interval), the querier SHOULD send a Session Query Interval TLV in subsequent LM queries indicating the interval chosen (greater than or equal to the minimum supported by the responder). On seeing the TLV from the querier the responder may cease including the = TLV, and on seeing the TLV not included in the response the querier may cease sending the TLV. This has the advantage of quickly finding an agreeable rate and always initiating a measurement without requiring the = administrator or querier to know the capabilities of the responder a priori. 15) In 4.1.1 it is noted that data from multiple intervals can be accumulated to provide a total loss measure. It should also be noted = that this data can be used to calculate a loss rate. 16) In 4.1.2 the querier sets counter 1 to the count of packets sent = before the LM query message. It could also indicate that this value may be set = to zero until the counting resources have been engaged (e.g., if waiting = for a favorable response from the responder before beginning the measurement process). 17) 4.1.5 should state that it is also possible to forward the final LM message (containing all counts) to another location for post-processing.

I am not very clear about the specific application of Fault management message. In section 2 of this document, it said " Fault OAM messages are generated by intermediate nodes where an LSP is switched". Does it mean that the fault message can only be used for alarm suppress of LSP layer? Could not this fault management function be used for PW layer, especially for the MS-PW conditions. Take the following hiberarchy scenario for example, PW1 and PW2 are two segments of the MS-PW which is client of the LSP layer. if the server layer of LSP fails, such as Link1, node2 will initiate AIS message and sent it to LSP1 end point node3. As MS-PW is client of LSP1, for this condition, whether Node3 will further initiate Fault management message to MS-PW end point Node4 to notify the failure of LSP1 to suppress alarm of the end to end pw service. IMO, Fault management function should cover these PW conditions. - MS-PW - - +---------AIS/LKR-------------->>- -<-----------------PW1-------------------->|-----------------PW2------------ >- - +----AIS/LKR---->> - -<-------LSP1---------+-------------------><--------------LSP2-------------- ->- - |AIS/LKR - -<--- Link1---------->|<--- Link2------><--------Link3--------------------->- Node1 Node2 Node3 Node4 Hope authors could clarify this point and detail the Fault function process about PW scenarios in this document.

Simplify it will be more smart. 2.section 4.1.2, the first sentence" This TLV carries the Interface Identifier as defined ......", "the Interface Identifier" should be "the Global Identifier". right? 3. section 5.3, there are two "that" in the first sentence, one is redundancy.

In the section 5.1, the third paragraph, it said "The message is then sent. The message MUST be refreshed two more times at an interval of one second. Further refreshes are sent according to the value of the refresh timer." I don't know why the refreshing massage must be first sent two more times in one second and then sent as the refresh timer interval. Is it ok if the refreshing massage is sent only according to the value of the refresh timer? If it is not, what problem may be introduced? Hope authors could explain it for me. In addition, figure 2 is about the fault management massage format, so I think naming the figure" MPLS-TP fault Management Message Format " other than" MPLS-TP OAM Message Format " is more suitable.

The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-oam-framework/ Technical Summary This MPLS-TP OAM Framework defines the mechanisms and procedures for alarm, fault, performance and protection-switching management for an MPLS based packet transport applications. Care has been taken to make sure the OAM for MPLS based packet transport networks is backwards compatible with existing MPLS OAM tools, New OAM mechanisms have only been defined when existing mechanisms are not sufficient to meet the MPLS-TP requirements. This document includes a comprehensive set of OAM procedures that satisfy the requirements mentioned above. The docement defines a set of functions that has great affinity with comparable functions in existing transport networks, e.g. SONET/SDH and OTN. The MPLS-TP OAM framework discusses mechanisms that are applicable to LSPs and/or (MS-)PWs. Co-routed and associated bidirectional p2p transport paths as well as unidirectional p2p and p2mp transport paths are within scope of the document. Working Group Summary Since the document is an output from the MPLS-TP project it is the joint output of several IETF working groups and Qustion 9, 10, 12 and 14 of ITU-T SG15.

With one exception, this text looks substantially the same to me as the last paragraph of Section 4.1.1. The exception is your addition of 'or the far end may not be able to support the requested measurement' to the first sentence, but that case is not what this text is meant to cover: if the far end doesn't support the requested measurement, the right thing to do is to reply with an appropriate error code so the querier knows what went wrong. > Section 3.5.3: It stated: > When a query is received with a Session Query Interval that is > too low for the receiver to support, the receiver SHOULD > include this object when it generates an error response. > > Question: > Which error code should be used? Is it 0x18:Error - Unsupported > Query Interval? If Yes, should add this to the sentence. Yes, that's the purpose of this error code. We can be explicit here. > What if the Querier indicates "0x2: No Response Requested"? In general, a no-response-requested measurement means that the querier can't receive any direct feedback; the assumption of this measurement mode is that control is achieved through some external means, e.g. an NMS that ensures consistent operation among the nodes involved. > Section 4.1.5: > * Should allow the Loss measurement to be calculated somewhere else, > in case the initiator (querier) doesn't have the capacity to do the > calculation. Ben Mack-Crane has made comprehensive comments on this topic, so we'll address it in that context. > * Should add a description that measurement is to be stopped when far > end not respond anymore.

You said:
"if the far end doesn't support the requested measurement, the right thing to do is to reply with an appropriate error code so the querier knows what went wrong."
 
What if the reply message got lost? Then you have to add the mechanism to make far-end sending multiple messages with the correct Error Code.
 
So the simplest thing is for the Querier to stop the measurement either upon receiving a reply with Error Code or not receiving any reply for a while.

With one exception, this text looks substantially the same to me as the
last paragraph of Section 4.1.1.  The exception is your addition of 'or
the far end may not be able to support the requested measurement' to the
first sentence, but that case is not what this text is meant to cover:
if the far end doesn't support the requested measurement, the right
thing to do is to reply with an appropriate error code so the querier
knows what went wrong.

Yes, that's the purpose of this error code.  We can be explicit here.
 
>       What if the Querier indicates "0x2: No Response Requested"?
 
In general, a no-response-requested measurement means that the querier
can't receive any direct feedback; the assumption of this measurement
mode is that control is achieved through some external means, e.g. an
NMS that ensures consistent operation among the nodes involved.

Ben Mack-Crane has made comprehensive comments on this topic, so we'll
address it in that context.
 
> * Should add a description that measurement is to be stopped when far
> end not respond anymore.
 
OK.
 
Thanks for your comments!

There should be no need for a separate activation flag or message. The last paragraph of Section 4.1.1 explains what the responder can do if it is not yet ready to provide counter data. It can simply not respond until it is ready, or it can respond with an appropriate notification code in the meantime (the appropriate code in this case would be Notification - Initialization In Progress, described in Section 3.1).

Sure. In essence, upon receiving a query requesting an unsupported operation, the responder SHOULD respond with an appropriate error code, and in general, the querier SHOULD time out any measurement attempt that's been outstanding for too long. We'll clarify this in the text.

Section 4.2.2, 4th paragraph, > " The Fpath field SHALL identify the path that is reporting the failure > condition (i.e. if protection path then Fpath is set to 0...". > Since PSC message are only transmitted on protection path, if protection > path has signal fail, the PSC message may not be able to be sent out to > far-end. As Yaacov has mentioned, we would like the PSC to send messages anyways in the chance that they may get through. This is explicitly noted in section 4.3.3.2: --- "When the domain is in unavailable state the PSC messages may not get through and therefore the protection is more dependent on the local inputs rather than the remote messages (that may not be received)." ---- Is that sufficient, or do you think we need additional text to reinforce this point? > 8. Section 4.3.3, I go through this part fast, a general question is: are > the PSC operations for 4 different protection types identical ? In this > section there is no description about operation of each specific > protection type, but to my understanding, there may be different > operations, e.g., for bidirectional 1:1 protection, the end point may need > to switch the sink selector and transmitting bridge simultaneously > according to some input, but for unidirectional 1:1 the end point may only > need to switch the transmitting bridge OR the sink selector. And the PSC > message sent may also be different for different protection types. (Please > correct me if there is anything wrong with this thought). PSC is not, in my view, tightly coupled to the four protection types. That is to say, PSC is a tool that allows the device vendor and network operator to build protection in an MPLS-TP network. This protection can be one of the four protection types you describe, but PSC is merely a protocol to accomplish the end goal. It may, for example, be possible in the future to use PSC to build one or more types of 1:n protection; when and if this is done, the message types would likely remain the same as they are now. eric >=20 >=20 > Best Regards, > Jie >=20 > > -----Original Message----- > > From: mpls-tp-bounces@ietf.org [mailto:mpls-tp-bounces@ietf.org] On > > Behalf Of Loa Andersson > > Sent: Thursday, February 03, 2011 7:42 PM > > To: mpls-tp@ietf.org;

Since a MEG pertains to a single MPLS-TP LSP, IP compatible MEG_IDs for MPLS-TP LSPs are simply the corresponding LSP_IDs. We note that while the two identifiers are syntactically identical, they have different semantics. This semantic difference needs to be made clear. For instance if both a MPLS-TP LSP_ID and MPLS-TP LSP MEG_IDs are to be encoded in TLVs different types need to be assigned for these two identifiers. =20 you can only detect wrong MEP ID, that's Unexpected MEP, it is not = Mis-merge. =20 If period negotiation is not used, how to insure interoperability with = BFD used in IP/MPLS asked always by providers?

Hi,

W.r.t ITU standard, Mismerge and Unexpect= ed MEP are identified as follows,

If a CCM frame w= ith same MEG Level but with a MEG ID different than the receiving MEP=E2=80= =99s own MEG ID is=C2=A0
received, Mismerge is detected.

=E2=80= =A2 If a CCM frame with the same MEG Level and a correct MEG ID but with an= incorrect MEP ID, including=C2=A0
receiving MEP=E2=80=99s own ME= P ID, is received, Unexpected MEP is detected.

I think, the authors should clearly=C2=A0differentiate=C2=A0= the unexpected MEP and Mismerge defects in the MPLS-TP OAM?

-- =
BR,
Venkat.

Hi Feng:

I'm not sure how unexpected MEP is not indicative of a mismerge. Either=
 the source MEP ID has been misconfigured, or you are receiving a message f=
rom a MEP due to LIB corruption or similar defect somewhere in the network.=
=20

As for your second point, it is not that negotiation is not used, there is =
simply no give and take allowed, so the procedures are simply modified slig=
htly in the TP case . If the far end refuses to support the requested perio=
dicity for whatever reason, you do not progress beyond the INIT state and p=
resumably send some indication to management that the session could not com=
e "UP". You have that option whether you are conformant to CC-CV-=
RDI draft or simply RFC 5884. So as far as I can tell interoperability opti=
ons exist, they were always there in the protocol, we are simply providing =
implementation guidelines for the TP application...

I hope this helps

HI Feng:

See section 7.1 of=C2=A0ht= tp://tools.ietf.org/html/draft-ietf-mpls-tp-identifiers-03=C2=A0. IM= O it is simply a terminology issue as to whether a MEG is encoded in the LS= P and PW formats or not.

Section 3.5.1 of the CC-CV-BFD draft identifies that period negotiat= ion is not used. So unexpected period occurs when one end unpexpectedly cha= nges the period advertised.

I hope this helps

=C2=A0=C2=A0=C2=A0=C2=A0 In 3.3. MPL= S BFD proactive CV Message format, LSP/PW MEP ID is defined without MEG, ho= w to detect Mismerge?

Mansfield, M. Daikoku, L. Wang Filename : draft-ietf-mpls-tp-security-framework-00.txt Pages : 25 Date : 2011-2-16 This document provides a security framework for Multiprotocol Label Switching Transport Profile (MPLS-TP). Extended from MPLS technologies, MPLS-TP introduces new OAM capabilities, transport oriented path protection mechanism, and strong emphasis on static provisioning supported by network management systems. This document addresses the security aspects that are relevant in the context of MPLS-TP specifically. It describes the security requirements for MPLS-TP; potential securities threats and migration procedures for MPLS-TP networks and MPLS-TP inter-connection to MPLS and GMPLS networks. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunication Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and PWE3 architectures to support the capabilities and functionalities of a packet transport network. This Informational Internet-Draft is aimed at achieving IETF Consensus before publication as an RFC and will be subject to an IETF Last Call.

Greg,

You are correct , the proposed update does not propose any changes to VCCV.
However the problem with vccv is not as simple as to ask for a new code point from IANA.
Given the good amount of discussion on this point, we should probably have a discussion in Beijing.

Dear Authors,
I think that proposed update of the Section 4.2. RFC 5586 makes it possible
to use GAL on MPLS-TP PW that uses Control Word. I consider it to be
conflict between PW VCCV CC types because use of GAL is not negotiated
through PW VCCV negotiation. To avoid such situation I propose:

   - in Section 5 request IANA to assign new CC Type "MPLS Generic
   Associated Channel Label"
   - assign precedence to new CC Type that affects Section 7 RFC 5085

to use GAL on MPLS-TP PW that uses Control Word. I consider it to be
conflict between PW VCCV CC types because use of GAL is not negotiated
through PW VCCV negotiation. To avoid such situation I propose:

   - in Section 5 request IANA to assign new CC Type "MPLS Generic
   Associated Channel Label"
   - assign precedence to new CC Type that affects Section 7 RFC 5085

Regards,
Greg

[Jie] Actually this comment is also about the first sentence in 4.1: "The PSC control packets SHALL be transmitted over the protection path only" IMO, If the transmitting end knows (either through remote PSC message or local information) the transmitting direction of the protection path is in fault, it may use working path to send PSC message. This way the PSC message would always be sent on only one path, and the remote end could still receive this message in protection path failure scenarios. > >> 7.

[Jie] As draft-sur-fwk specified, "For bidirectional P2P paths, both unidirectional and bidirectional protection switching are supported." So an example is one end of the bidirectional path receives local signal fail on working path. This would normally be a failure in receiving direction on working path. For 1:1 unidirectional protection, the protection actions in each direction are independent, then maybe one direction has switched to the protection path, while in the opposite direction the traffic is still on the working path. In this case the output PSC message should indicate the remote end to switch the transmitting bridge to protection path and keep the remote selector bridge unchanged. For this the "Path" Field may need to be extended to TxPath and RxPath, and the PSC message with the format REQ(Fpath, TxPath, RxPath) would be SF(1,0,1). If later a remote signal fail on working path is received, then the output message would be changed to SF(1,1,1). For 1+1 bidirectional protection, the output PSC message should indicate the remote end to switch both the transmitting bridge and the selector bridge to protection path. Thus the output message would be SF(1,1,1). Thus IMO for unidirectional and bidirectional protection the action would be different, and the messages may need be different to convey clear information.

However, given PWs are being carried forward into MPLS-TP then we also have= to deal with the issue that CP/MP of a transport network needs to logicall= y OOB wrt to the DP traffic. The GAL provides this function for the MPLS-T= P layer network itself (though it also gets this a wee bit wrong by asking = it to play a DP OAM role too,) but what about the PW layer network? MS PWs for sure are their own/different layer network....so they will need = their own access point addressing, OAM, routing, signalling, etc. I asked = some time ago why we were not using RSVP signalling here but T-LDP instead.= ..and I was told that RSVP cannot handle the PW signalling messages (nor th= e access addressing formats I assume...and we will of course need a new ins= tance of routing that will). So how is T-LDP being taken OOB wrt to the PW DP? regards, Neil Neil Harrison BT Design Tel: +44 (0) 1 803 812 545 Email: neil.2.harrison@bt.com Web: www.bt.com This email contains BT information, which may be privileged or confidential= .

Sasha/Greg,

 

I would certainly agree that the use of the GAL wit= h PWs is wrong....but the reason for that is simply that PWs per se violate the w= hole purpose of MPLS-TP as a *transparent* transport network, noting that a true transport network must treat all client symbols equally...that is just a fact. 

 

However, given PWs are being carried forward into M= PLS-TP then we also have to deal with the issue that CP/MP of a transport network needs to logically OOB wrt to the DP traffic.  The GAL provides this function for the MPLS-TP layer network itself (though it also gets this a w= ee bit wrong by asking it to play a DP OAM role too,) but what about the PW la= yer network?

 

MS PWs for sure are their own/different layer network....so they will need their own access point addressing, OAM, routin= g, signalling, etc.  I asked some time ago why we were not using RSVP signalling here but T-LDP instead...and I was told that RSVP cannot handle = the PW signalling messages (nor the access addressing formats I assume...and we will of course need a new instance of routing that will).

 

So how is T-LDP being taken OOB wrt to the PW DP?

 

regards, Neil

Dear Authors and All,
prior to the meeting in Bejing and acceptance of this proposal as WG docume= nt Luca and I agreed that use of GAL with PW VCCV presents a problem.
I was not attending the IETF-79, nor I found discussion of this issue in th= e minutes. I think that this issue should be specified, explained. In my view= , this document updates not only RFC 5586
but RFC 5085 too.

Regards,
Greg

This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : Label Distribution Protocol Extensions for Point-to-Multipoint and Multipoint-to-Multipoint Label Switched Paths Author(s) : I. Minei, et al. Filename : draft-ietf-mpls-ldp-p2mp-12.txt Pages : 39 Date : 2011-02-18 This document describes extensions to the Label Distribution Protocol (LDP) for the setup of point to multi-point (P2MP) and multipoint-to- multipoint (MP2MP) Label Switched Paths (LSPs) in Multi-Protocol Label Switching (MPLS) networks. These extensions are also referred to as Multicast LDP (mLDP). mLDP constructs the P2MP or MP2MP LSPs without interacting with or relying upon any other multicast tree construction protocol. Protocol elements and procedures for this solution are described for building such LSPs in a receiver-initiated manner. There can be various applications for P2MP/MP2MP LSPs, for example IP multicast or support for multicast in BGP/MPLS L3VPNs. Specification of how such applications can use a LDP signaled P2MP/ MP2MP LSPs is outside the scope of this document.

Would love to hear comments and feedback from the WG. The draft is available here: http://www.ietf.org/id/draft-jjb-mpls-rsvp-te-hsmp-lsp-00.txt Abstract In Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) environment, the RSVP-TE based Point-to-Multipoint (P2MP) LSP allows traffic to transmit from root to leaf node, but there is no co-routed reverse path for traffic from leaf to root node. This draft introduces a Hub and Spoke Multipoint (HSMP) LSP, which allows traffic from both the root to the leaves through a P2MP LSP and also the leaves to the root along a co-routed reverse path.

I see at least two issues:
  • use of GAL for PW, in m= y view, is another VCCV CC type that has to be negotiated as described in R= FC 5085.
  • use of GAL creates ambiguous situation when PW CW is used.= The benefit from extending GAL in PW, as I see, is for PWs that are not re= quired to use PW CW. That might be a good enough reason to update RFC 5586 = as proposed in the document but we must address use cases of GAL in PWs tha= t require presence PW CW. If we prohibit or even discourage use of GAL for = these PWs that have PW VCCV as native Associated Channel, then architecture= of ACh for MPLS-TP PW not simplified as result of adopting the proposal.

Dan,

I agree with you that the initial LM query message may be treate= d as counting
activation message, but that requires the responder to different= iate the first
LM query and other LM queries, and it's still not sure how to sw= itch off the
counting function at the responder when the LM function finished= .

To put it another way, the initial query message is itself the signal t= o

it to begin generating useful responses.  Such actions may include=
"switching on the counting function" or anything else, and ar= e

List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 22 Feb 2011 01:19:36 -0000 A new Request for Comments is now available in online RFC libraries. RFC 6138 Title: LDP IGP Synchronization for Broadcast Networks Author: S. Kini, Ed., W. Lu, Ed. Status: Informational Stream: IETF Date: February 2011 Mailbox: sriganesh.kini@ericsson.com, wenhu.lu@ericsson.com Pages: 9 Characters: 20161 Updates: RFC5443 I-D Tag: draft-ietf-mpls-ldp-igp-sync-bcast-06.txt URL: http://www.rfc-editor.org/rfc/rfc6138.txt RFC 5443 describes a mechanism to achieve LDP IGP synchronization to prevent black-holing traffic (e.g., VPN) when an Interior Gateway Protocol (IGP) is operational on a link but Label Distribution Protocol (LDP) is not. If this mechanism is applied to broadcast links that have more than one LDP peer, the metric increase procedure can only be applied to the link as a whole but not to an individual peer. When a new LDP peer comes up on a broadcast network, this can result in loss of traffic through other established peers on that network. This document describes a mechanism to address that use-case without dropping traffic. The mechanism does not introduce any protocol message changes. This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

EO# We discussed this early on when writing the draft, but decided against it. The concern was that providing multiple channels to send a message on could open us up to complications and race conditions. What happens, for example, if you get different messages on the W and P SPMEs, for example? I see your point about only sending the message on one path, but there are some types of failure where one end could think an SPME is down and the other might not. What happens if the rx node thinks the P SPME is down (and thus expects messages on the W SPME), but the tx node thinks the P SPME is up, and thus does not send anything on the W SPME? Bottom line is that there are always going to be ugly cases we can't easily resolve, especially with the constraint that this protocol must be fairly simple; the more dynamic it is, the longer it will take to react to a failure, and in a protection protocol that's not something we can afford. > > > 8.

Which field(s) would be different? What functionality would these fields provide that can't be provided with PSC as defined in our draft? As part of the PSC work we looked at other protection protocols (you may notice a striking similarity to APS), and I didn't see any type-specific redefinition of fields in those. eric >=20 >=20 > Best regards, > Jie >=20 > > > > > > > -----Original Message----- > > > > From: mpls-tp-bounces@ietf.org [mailto:mpls-tp-bounces@ietf.org] > > > > On Behalf Of Loa Andersson > > > > Sent: Thursday, February 03, 2011 7:42 PM > > > > To: mpls-tp@ietf.org; mpls@ietf.org > > > > Cc: ahmpls-tp@lists.itu.int > > > > Subject: [mpls-tp] mpls wg last call on > > > draft-ietf-mpls-tp-linear-protection-04 > > > > > > > > Working Group, > > > > > > > > this is to start a four week working group last call on "MPLS-TP > > > > Linear Protection" (draft-ietf-mpls-tp-linear-protection-04). > > > > > > > > Please send comments to the mpls-tp@ietf.org mailing list. > > > > > > > > This working group last call ends on February 28, 2011. > > > > > > > > > > > > > > > > Loa, George and Ross > > > > > > > > MPLS wg co-chairs > > > > > > > > > > > > > > > > -- > > > > > > > > > > > > Loa Andersson email: > > > > loa.andersson@ericsson.com > > > > Sr Strategy and Standards Manager loa@pi.nu > > > > Ericsson Inc phone: +46 10 717 52 13 > > > > +46 767 72 92 13 > > > > _______________________________________________ > > > > mpls-tp mailing list > > > > mpls-tp@ietf.org > > > > https://www.ietf.org/mailman/listinfo/mpls-tp > > > > > > > > > > > > _______________________________________________ > > > mpls-tp mailing list > > > mpls-tp@ietf.org > > > https://www.ietf.org/mailman/listinfo/mpls-tp From takeda.tomonori@lab.ntt.co.jp Wed Feb 23 20:39:00 2011 Return-Path: X-Original-To: mpls@core3.amsl.com Delivered-To: mpls@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 8D4FC3A6968; Wed, 23 Feb 2011 20:39:00 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -98.89 X-Spam-Level: X-Spam-Status: No, score=-98.89 tagged_above=-999 required=5 tests=[BAYES_00=-2.599, HELO_EQ_JP=1.244, HOST_EQ_JP=1.265, J_CHICKENPOX_13=0.6, J_CHICKENPOX_21=0.6, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id lGGJG-92sssF; Wed, 23 Feb 2011 20:38:59 -0800 (PST) Received: from tama500.ecl.ntt.co.jp (tama500.ecl.ntt.co.jp [129.60.39.148]) by core3.amsl.com (Postfix) with ESMTP id 53EAF3A6953; Wed, 23 Feb 2011 20:38:59 -0800 (PST) Received: from mfs6.rdh.ecl.ntt.co.jp (mfs6.rdh.ecl.ntt.co.jp [129.60.39.149]) by tama500.ecl.ntt.co.jp (8.14.4/8.14.4) with ESMTP id p1O4dlWD007905; Thu, 24 Feb 2011 13:39:47 +0900 (JST) Received: from mfs6.rdh.ecl.ntt.co.jp (localhost [127.0.0.1]) by mfs6.rdh.ecl.ntt.co.jp (Postfix) with ESMTP id 0B17065F9; Thu, 24 Feb 2011 13:39:47 +0900 (JST) Received: from imail2.m.ecl.ntt.co.jp (imail2.m.ecl.ntt.co.jp [129.60.5.247]) by mfs6.rdh.ecl.ntt.co.jp (Postfix) with ESMTP id 046BB65F1; Thu, 24 Feb 2011 13:39:47 +0900 (JST) Received: from [127.0.0.1] ([129.60.80.55]) by imail2.m.ecl.ntt.co.jp (8.13.8/8.13.8) with ESMTP id p1O4dYV4001648; Thu, 24 Feb 2011 13:39:46 +0900 Message-ID: <4D65E0F6.7050004@lab.ntt.co.jp> Date: Thu, 24 Feb 2011 13:39:18 +0900 From: Tomonori TAKEDA User-Agent: Thunderbird 2.0.0.9 (Windows/20071031) MIME-Version: 1.0 To: ccamp@ietf.org, pce@ietf.org, mpls@ietf.org, mpls-tp@ietf.org Content-Type: text/plain; charset=ISO-2022-JP Content-Transfer-Encoding: 7bit Subject: [mpls] iPOP 2011 submission deadline extended to March 4 X-BeenThere: mpls@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: Multi-Protocol Label Switching WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 24 Feb 2011 04:39:00 -0000 (Apologies if you receive multiple copies of this message.)

The root cause of our problem was the presence of empty "AddressList" TLV in LDP MacWithdraw message. Vendor "C" inserts this TLV in every MAC Withdraw message even if there are no addresses to withdraw. Their explanation: --- "RFC 4762 introduces the MAC List TLV as an optional TLV to the Address Withdraw message, used to withdraw MAC addresses. The addition of this optional TLV to the Address Withdraw message does not replace the Address List TLV. While it would be perfectly acceptable to withdraw both IPV4 addresses as well as MAC addresses in the same Address Withdraw message, it's not always the case that there is a need to withdraw IPV4 addresses at the same time that there is a need to withdraw MAC addresses. Also, given that the Address List TLV can not be omitted when sending an Address Message that withdraws MAC Addresses, the logical conclusion is to send an empty Address List TLV in the Address Withdraw message, along with the MAC List TLV. The empty address list TLV, while not explicitly specified, is not explicitly prohibited either. It would have been better had the RFCs been explicit on this subject, but the above logic is the best solution given the way that the RFCs are written." --- Vendor "J" implies, that "AddressList" TLV is not mandatory in MACWithdraw message. They omit this TLV in their messages. However, in addition, they perform a strange check for minimal TLV length in all incoming messages. Because of this check empty AddressList TLV (with length=2) considered as "Malformed TLV" and the session goes down. I haven't found any mention about checking for "too short TLV" in RFC 5036. However, point #11 in chapter "7. Changes from RFC 3036" states: --- 11. Added case for TLV length too short in the specification for handling malformed TLVs. --- It would be great to know your opinion about these questions: 1. The presence of empty AddressList TLV in MACWithdraw message. Is it mandatory or optional? 2. Checking incoming TLVs for minimal length. Is it correct behavior ? IMHO, it should be remembered about Jon Postel's law: "Be liberal in what you accept, and conservative in what you send" -- Best regards, Egor Zimin From zhang.fei3@zte.com.cn Sun Feb 27 17:33:12 2011 Return-Path: X-Original-To: mpls@core3.amsl.com Delivered-To: mpls@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id C417A3A6961; Sun, 27 Feb 2011 17:33:12 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -100.349 X-Spam-Level: X-Spam-Status: No, score=-100.349 tagged_above=-999 required=5 tests=[BAYES_05=-1.11, HTML_MESSAGE=0.001, RCVD_DOUBLE_IP_LOOSE=0.76, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Q9JuQv6RYP2F; Sun, 27 Feb 2011 17:33:11 -0800 (PST) Received: from mx5.zte.com.cn (mx5.zte.com.cn [63.217.80.70]) by core3.amsl.com (Postfix) with ESMTP id D3CD13A695E; Sun, 27 Feb 2011 17:33:10 -0800 (PST) Received: from [10.30.17.100] by mx5.zte.com.cn with surfront esmtp id 205952043691617; Mon, 28 Feb 2011 09:28:59 +0800 (CST) Received: from [10.30.3.20] by [192.168.168.16] with StormMail ESMTP id 47420.2043691617; Mon, 28 Feb 2011 09:24:55 +0800 (CST) Received: from notes_smtp.zte.com.cn ([10.30.1.239]) by mse01.zte.com.cn with ESMTP id p1S1Xsf6038947; Mon, 28 Feb 2011 09:33:54 +0800 (GMT-8) (envelope-from zhang.fei3@zte.com.cn) To: ccamp@ietf.org, mpls@ietf.org, mpls-tp@ietf.org MIME-Version: 1.0 X-KeepSent: 3D2BCB7D:7BE0C902-48257845:00045755; type=4; name=$KeepSent X-Mailer: Lotus Notes Release 6.5.6 March 06, 2007 Message-ID: From: zhang.fei3@zte.com.cn Date: Mon, 28 Feb 2011 09:34:00 +0800 X-MIMETrack: Serialize by Router on notes_smtp/zte_ltd(Release 8.5.1FP4|July 25, 2010) at 2011-02-28 09:33:53, Serialize complete at 2011-02-28 09:33:53 Content-Type: multipart/alternative; boundary="=_alternative 0008966748257845_=" X-MAIL: mse01.zte.com.cn p1S1Xsf6038947 Subject: [mpls] draft-zhang-mpls-tp-rsvpte-ext-associated-lsp-03 X-BeenThere: mpls@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: Multi-Protocol Label Switching WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 28 Feb 2011 01:33:13 -0000 This is a multipart message in MIME format. --=_alternative 0008966748257845_= Content-Type: text/plain; charset="US-ASCII" Dear All We just updated the document about the creating of associated bidirectional LSPs, and below is the link: http://tools.ietf.org/id/draft-zhang-mpls-tp-rsvpte-ext-associated-lsp-03.txt Compared with last version, the main changes are about the section of asymmetric associated bidirectional LSP: We used the object UPSTREAM_TSPEC to trigger the peer end to set up the reverse unidirectional LSP in last version, however the application scenario defined in http://tools.ietf.org/html/draft-ietf-ccamp-asymm-bw-bidir-lsps-bis-01 is different from here.

Dear All

We just updated the document about the creating of associated bidirectional LSPs, and below is the link:

http://tools.ietf.org/id/draft-zhang-mpls-tp-rsvpte-ext-associated-lsp-03.txt

Compared with last version, the main changes are about the section of asymmetric associated bidirectional LSP:

We used the object UPSTREAM_TSPEC to trigger the peer end to set up the reverse unidirectional LSP in last version, however the application scenario defined in http://tools.ietf.org/html/draft-ietf-ccamp-asymm-bw-bidir-lsps-bis-01 is different from here. So a new object called REVERSE_TSPEC is used to replace the UPSTREAM_TSPCE object in this version.

The other revisions are structural and editoral in nature, such as complementing more considerations about security, adding one sub-section of informativereference, temporarily moving George from the position of co-authors....
The authors would like to have more feedback from the mailing list before pushing this work forward.

Grateful if you could review the document and post comments on the mailing list.

Thanks,

Nick

All:

 

Per the = direction of the PWE3 working group, beginning in IETF77 and reinforced = in IETF78, the PWE3 working group is conducting a Service Provider = implementation survey related to:

 

-          = Pseudowire Encapsulations

-          = Control Word Support

-          = Control Word Use

-          = VCCV Control Channel Support

-          = VCCV Control Channel Use

 

http://www.surveymonkey.com/s= /pwe3

 

This is a short survey directed toward Service = Providers who currently operate networks using any of the defined PWE3 = encapsulations.  The results of this survey will be used to = determine the direction of the Control Word support in current and = future encapsulations as well as solutions to VCCV interoperability = challenges.

 

We sincerely urge all service providers to = participate.  We ask that all equipment providers encourage = participation by their Service Provider customers.  The more = feedback we receive, the better view of the existing network we can have = on which to base going-forward direction.

 

If you have = any questions, regarding the survey, especially of a technical nature, = please contact me.  If you have non-technical questions, feel free = to reach out to the PWE3 WG chairs and myself.

 

The results = of the survey will be aggregated and shared at a high level.  No = low-level details of network implementations will be shared.  All = participant’s responses will remain private, if not = anonymous.

 

All responses will require a valid email address to = help ensure the survey’s validity.

 

Thanks,

Nick
