Agenda

PCE Working Group Meeting - Tuesday, March 29, 2011, 9:00 AM

1. Introduction

1.1. Administrivia, Agenda Bashing (chairs, 5 min) [5/120]

- IPR Statement, people need to review and consider IPR must be disclosed as early as possible.

1.2. WG Status (chairs, 10 min) [15/120]

- One new RFC (RFC6123) since IETF79.  
- draft-ietf-pce-inter-layer-ex expired. Fatai Zhang is discussing work with authors.
- draft-ietf-pce-pcep-mib expired. Dan King (as co-author) requested feedback and implementer experience to help move the draft forward.
- Cyril Margaria mentioned ongoing discussions occurring between the authors of draft-ietf-pce-gmpls-aps-req and draft-ietf-pce-vendor-constraints.
- The WG were asked to consider if draft-ietf-pce-vpn-req is ready to be closed based on current VPN solution documents. 

1.3. PCEP Port Issue (chairs + Ramon Casellas, 10 min) [25/120]

- It seems text regarding the source port was introduced between version 13 and 14 of the document. This was to address a specific source port security issue. Considering this is a legacy requirement and there was broad agreement that there is no longer a need to impose the source port. The co-chairs agreed under the proviso that it needs to be discussed with a security expert first.

2. GMPLS

2.1. PCEP Extensions for GMPLS (Cyril Margaria, 10 min) [35/120]

draft-ietf-pce-gmpls-pcep-extensions-02

- Co-chairs mentioned there was good progress and it was obvious good that the proposed change is backwards compatible. They also suggested that the authors check the draft with a security expert and then the work can move forward.

- Co-chairs felt that the protection object needs further consideration.

2.2. PCEP Requirement for RWA (Young Lee, 5 min) [40/120]

draft-ietf-pce-wson-routing-wavelength-03

- Lou Berger as CCAMP co-chair asked PCE co-chairs if they felt impairments should be progressed in the PCE WG. The PCE co-chairs mentioned they are open to proposals.

2.3. PCEP Extensions for RWA (Oscar Gonzales de Dios, 10 min) [50/120]

draft-lee-pce-wson-rwa-ext-01

- Co-chairs felt the draft was a little early for WG adoption. Some additional work on consistency with and reference to draft-ietf-pce-gmpls-pcep-extensions is expected.

- Co-chairs made a general observation that proposed extensions need strong justification, new protocol work that only offers very slight optimization is not so beneficial.

3. Multi-Domain

3.1. Representation of Domain Sequence (Dhruv Dhody, 10 min) [60/120]

draft-dhody-pce-pcep-domain-sequence-00

- Co-chairs polled the room and two people had read the draft. They suggested the author should try to trigger more discussion on the mailing list.

3.2. BRPC Extensions for Inter-AS Bidirectional LSPs (Xuerong Wang, 10 min) [70/120]

draft-wang-pce-inter-as-extentions-00

- It was mentioned that BRPC [RFC54441] can be used, and asked why these protocol extensions are required. Authors were requested to scope the problem in more detail.

3.3. Forward Search Path Computation for P2P and P2MP (Huaimo Chen, 20 min) [90/120]

draft-chen-pce-forward-search-p2p-path-computation-00

draft-chen-pce-forward-search-p2mp-path-00

- The author was asked to justify the motivation and benefits of this solution, especially considering well-known solutions which already exist.
- Path Key was proposed by the author as a collaborative technique for maintaining domain confidentially. 
- Due to a failure in WG CSMA/CD during Q&A session, the co-chairs will also raise some points on the WG list.

3.4. Path Key MIB (Dhruv Dhody, 5 min) [95/120]

draft-dhody-pce-pcep-pathkey-mib-01

- The co-chairs polled the group to see who has implemented. There was one implementer attending the session.

4. Miscellaneous

4.1. Backup Node Computation (Huaimo Chen, 5 min) [100/120]

draft-chen-pce-compute-backup-ingress-01

draft-chen-pce-compute-backup-egress-01

- Author was asked why this functionality cannot be achieved using existing mechanisms like XRO.
- Author was also asked to consider the impact of this solution on a network that uses fast-reroute.
- The general consensus was the solutions require further investigation and documentation and the motivation also needs to be documented.

4.2. Open Mic: Charter Update (all, 20 min) [120/120]

- New WG items including TED mechanisms and alternatives may be proposed for the new charter. Please provide feedback and suggestions on the list.
- WG was asked to review the recharter text and provide feedback ASAP, ideally by April 10, 2011.
- Authors of drafts specifically mentioned as milestones on the new recharter proposal, should review the milestone dates and provide feedback if they disagree with said dates.
