Liaison statement received from ITU-T SG15

["Adrian Farrel" <adrian@olddog.co.uk>]

Hi,

We have received a liaison statement from SG15.
You can find it in some magic proprietary encoding format at
http://www.olddog.co.uk/incoming.htm

It will find its way to the IETF liaison web site in due course.

The main text is below.

Q.14/15 would like to thank the IETF CCAMP WG and especially the members of the ASON
Routing Requirements Design Team for their efforts to understand and capture ASON Routing
Requirements for the future work in IETF.
Q.14/15 would like to continue cooperative work with IETF, extending this to the
application of routing protocols to support the ASON requirements.  Q.14/15 is now at the
point of analyzing existing routing protocols such as OSPF, IS-IS and PNNI for their use
in ASON and would like to work with the associated bodies to understand the possible
implications on the routing protocols.  As further information, Q.14/15 is forwarding the
attached routing template to support this work. The routing template contains extracts of
ASON documents containing requirements on routing protocols.  It is considered stable text
and is intended to be used as a tool to assess candidate routing protocols against ASON
routing requirements.

It is suggested that a cross-body design team similar to the team created to capture ASON
Routing Requirements may be created to investigate use of IETF routing protocols for ASON.

We note that special attention may need to be focused on the following (numbers in
parentheses are the associated requirements listed in the routing template):

-- identification of SNPP endpoints in link advertisement (Req. 1775-81)

-- advertisement of endpoint reachability (Req. 1772)

-- advertisement of available connections at a particular signal type (Req. 1789)

-- distinguishing information received from another level in a routing hierarchy (Req.
1767)



Q.14/15 would also like to note for IETF the recent completion of the following ITU-T
work:

-- approval of ITU-T Recommendation G.7715.1 on Link State Routing Protocol Requirements
for ASON

-- consent of an amendment to ITU-T Recommendation G.7713 on Distributed Call/Connection
Management



An interregnum meeting of Q.14/15 has been planned for 1 - 5 November 2004, located in
Berlin, Germany.  The Rapporteur for Q.14/15 invites the participation of the CCAMP WG in
related discussions.  Details of the agenda will be provided prior to the meeting. For
those interested in further information and/or attending the interregnum meeting should
contact the Rapporteur for Q.14/15 (H. Kam Lam, hklam@lucent.com) by 24 September 2004.
Any contributions directed to the meeting must be submitted by 25 October 2004.
