Description of Working Group:

Fibre Channel is a high speed network technology primarily used for
storage networking (i.e., Storage Area Networks [SANs]). Two
important aspects of Fibre Channel interact with the Internet:
        - Fibre Channel can encapsulate and carry IP protocol traffic
        - Fibre Channel devices can be managed via SNMP

The Internet and Management Support for Storage WG (imss) is chartered
to address two areas, specifically:
        - IPv4 over Fibre Channel has been specified in RFC 2625. A
          corresponding specification for IPv6 is needed.
        - An initial Fibre Channel Management MIB has been developed by
          the IP Storage (ips) WG; extensions are needed to encompass
          management of additional aspects of Fibre Channel, such
          as zoning.

In the future, other storage related MIBs for other storage transports
such as INCITS T10 Serial Attached SCSI (SAS) or SCSI command specific
MIBs may be proposed. This group would work with the appropriate
technical committee(s) in a manner similar to that described for
T11 below.

As Fibre Channel standardization is handled by the INCITS T11 Technical
Committee (http://www.t11.org), a close working relationship with T11
is essential to the WG's success. In particular:
      - The IPv6 over Fibre Channel specification will be based on
        draft-desanti-ipv6-over-fibre-channel-02.txt. This draft
        was originally developed within a T11 study group and T11
        has officially recommended this draft to the IETF.
      - The WG will not standardize management of Fibre Channel 
        features ahead of their incorporation into appropriate T11
        Fibre Channel standards.
      - The WG will work closely with T11, specifically Task Group
        T11.5, on the functionality and structure of the MIBs it     
        develops for management of Fibre Channel.

In addition to working closely with the INCITS T11 Technical
this Working Group will work closely with IETF IPv6 Working Group as
appropriate. In particular, the IPv6 Working Group will be kept
informed on the progress and status of the IPv6 over Fibre Channel
specification. The IMSS Working Group Last Call announcement will be
cross-posted to the IPv6 WG mailing list.

Goals and Milestones:

Done  Submit IPv6 over Fibre Channel draft to IESG for consideration as Proposed Standard
Oct 04  Submit Fibre Channel Domain Manager MIB to IESG for consideration as Proposed Standard
Oct 04  Submit Fibre Channel Name Server MIB to IESG for consideration as Proposed Standard
Nov 04  Work with T11.5 to determine what additional MIB modules are needed
Jan 05  Submit Extensions for Fibre Channel Interfaces MIB to IESG for consideration as Proposed Standard
Jan 05  Review working group charter and determine what additional work, if any, should be undertaken by working group

    Blue sheets
    Note Well
    WG Chair to change - Elizabeth Rodriguez is stepping down
    Milestones (WG charter page needs to be updated)
    Draft status (publication to be requested soon for IP over FC, Fabric Address Manager MIB, Name Server MIB - awaiting PROTO writeup)
    T11.5 Status, including new Fibre Channel MIBs for IMSS: 30 min [B]
    Roger Cummings (Symantec, T11.5 chair)
    Ready Now:
    - FSPF MIB (draft-kzm-imss-fc-fspf-mib-02.txt) [T11.5 SM-FSM]
    - Routing Info MIB (draft-kzm-fc-rtm-mib-03.txt) [T11.5 SM-RTM]
    - Accepted as imss WG official drafts/work items. Have been reviewed by Fibre Channel experts in T11.5 .

    Coming soon:
    - Virtual Fabric MIB (draft-kipp-fc-vitual-fabrics-mib-01.txt) [SM-VFM]
    - Accepted as imss WG official drafts/work items pending an official
    T11.5 vote to approve forwarding this MIB to the imss WG next week.
    Has been reviewed by Fibre Channel experts in T11.5 .
    (Near) Future:
    - Zone Server MIB
    - RSCN MIB
    - Fabric Configuration Server MIB
    - Initial work in T11.5 . No additional Fibre Channel MIBs beyond these are currently anticipated.
    FSPF MIB and Routing Info MIB (Keith McCloghrie, Cisco) [C]
    See Keith's slides for info on MIB structure and contents.
    WG chair or designate will send note to list asking for reviews of these MIBs as step towards WG Last Call.
    Virtual Fabric MIB (Scott Kipp, McData) [D]
    See Scott's slides for info on MIB structure and contents.

    FLIP (FAIS Line Interface Protocol) Conceptual Discussion: 30 min [E]
    Roger Cummings (Symantec, T11.5 chair)
    FLIP would be an RPC interface to the FAIS API for intelligent switches. Structure of an intelligent FC switch has some high level similarities to a router with fast-path and slow-path - the function here is to program the fast path and implement the slow-path.
    IETF could bring expertise in protocols to bear on this, but not much in the way of functional expertise.
    Will need to figure out how this relates to IETF netconf work.
    Roger will generate more context and details on this - probably a short I-D for the next IETF meeting, preceded by discussion on the imss mailing list.
