  1. ITU-T/OIF Report IETF 69 – Chicago – July ‘07 L. Ong (Ciena) lyong@ciena.com

  2. OIF • Met April 07 • Planned September Demo (ECOC ’07) • Multiple vendors and carrier labs • Focus on UNI and E-NNI Ethernet service support • Also demonstration of control plane reliability • Progress on UNI 2.0, E-NNI signaling 2.0 and interworking documents • Close to completion of UNI 2.0 • Incorporating IETF work on MEF service support • One liaison to this meeting • Interlayer Model – input to VCAT work in CCAMP

  3. OIF Liaison • Interlayer Model • Based on current ASON work at ITU-T • Discusses abstraction of server layer capabilities • Possible multiplexing at client or server layer • Addressing issues and establishment of signaling adjacencies at the client layer • Some aspects of the model prototyped for Interop • Separate SONET/SDH and VCAT hierarchical layers • Differs from current VCAT draft • Allows flexible reallocation of paths to VCGs • VCAT Tspec used to identify VCAT requirements • Need something similar to proposal in VCAT draft • At SONET/SDH layer, use NVC or MT?

  4. ITU-T • SG 15 Meeting 6/07 • Four liaisons to CCAMP • relationship between ITU and IETF • looping issue • VCAT signaling • GMPLS calls

  5. ITU-T Liaison #1 • Response to CCAMP liaison on Cooperative Relationship • general issues • will be discussed in ITU-IETF management team meeting • concerns • Q.14 believes there is an urgent need for cooperation in completing routing extensions to meet ASON requirements • Q.14 wishes to work cooperatively with CCAMP to develop protocol solutions that are of value to the industry

  6. ITU-T Liaison #2 & 3 • #2: Response to IETF liaison on looping • Notes ASON architecture may introduce additional issues • Hierarchical routing levels • need to understand parent vs. child relationship is critical • Concerns with Area ID-based approach • overhead of storing and passing Area IDs, • difficulty in changing an Area ID • #3: Response to IETF Liaison on VCAT draft • Notes that ITU has not seen updated draft since -02 • waiting on this for further comments

  7. ITU-TLiaison #4 • #4: Response to IETF liaison on GMPLS Calls • Comments from reading draft-ietf-ccamp-gmpls-rsvp-te-call-04.txt • Call Identifier • Note Call identifier format in G.7713.x and class num in RFC 3474 for G.7713.2 • Call destination • Note UNI Transport Resource Identifier in G.8080 and class num in RFC 3476 for G.7713.2 • Equivalent should be included in future ASON applicability draft • Usage of these would not pose problems for RSVP instances that did not process calls
