  2. ITU-T Q14/15 – Optical Control Plane Management Framework Discovery Architecture G.fame G.disc_arch Auto- discovery Initialization & Recovery Signaling Routing DCN/SCN G.7716 G.7714 Protocol Neutral Requirements (Detailed) G.7713 G.7715 G.7712 G.7715.1 G.7713.1 Protocol Specifications G.7714.1 G.7713.2 G.7713.3 ITU-T SG 15, Question 14 ASON Control & Management Recommendations

  3. Location of Relevant Information • The consented text for New Recommendations G.7715.1 and living lists for G.7714.1 and G.7713 can be obtained from: • ftp://sg15opticalt:otxchange@ftp.itu.int/tsg15opticaltransport/COMMUNICATIONS/index.html • http://www.ietf.org/iesg/liaison.html

  4. Liaisons from Q14/SG15 ITU main meeting-Geneva, Oct 21-31, 2003 • Liaison Statement To IETF CCAMP on RSVP-TE and CR-LDP • ASON Status

  5. Liaison Statement To IETF CCAMP on RSVP-TE and CR-LDP • ITU Question 14 of Study Group 15 thanks you for your liaison in which you notified us of the survey taken of implementers of GMPLS constrained LSP signalling. • As Recommendation G.7713.3 is currently in force, we will continue to have a normative reference to CR-LDP [RFC 3212]. • Your liaison has raised a concern regarding on-going maintenance of the CR-LDP code point space. We expect that future requests for code points in the range allocated to CR-LDP (0x0800 to 0x08FF) in [RFC 3212] will be granted based on “IETF Consensus” as defined in RFC 2434.

  6. ASON Updates • SG 15 has consented G.7715.1/ Y.1706.1 “ASON Routing Architecture and requirements for Link State protocols”. • This Recommendation provides architecture and requirements for a link state realization of G.7715/Y.1706 and G.8080/Y.1304 and is protocol neutral. This may be of assistance to the ASON Routing Requirements design team. • There were no changes made to Discovery Recommendations. • However, new issues were included in the G.7714.1 living list such as an Interoperable solution for ECC based discovery mechanisms. Question 9 of SG15 is assessing G.7714.1 discovery methods in the context of the existing equipment Recommendation G.783. • Two new draft recommendations related to Control Plane functions are being developed in SG15. • G.fame, “Framework for ASON management” • G.7716, “Control plane initial establishment, reconfiguration and recovery”. • In signalling, a number of study points were added to the living list of G.7713 “Distributed call and connection management”. • These include feedback, interaction with Vcat/LCAS, separation of call and connection parameters, and signalling resilience.

  7. ASON Updates • Next Q.14/15 interim meeting • 16 – 20 February 2004, located in North Carolina, USA. • 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. • Interested should contact the Rapporteur for Q.14/15 (H. Kam Lam, hklam@lucent.com) by 13 January 2004. • Any contributions directed to the meeting must be submitted by 9 February 2004.
