Overview GMPLS E-NNI 1.0 UNI A B C ASON #1 ASON #2 UNI E-NNI 1.0

Project Start Objective:  Generate an design guideline document for the interoperability of OIF/ITU-T ASON and IETF/GMPLS network domains Scope  E-NNI, I-NNI(GMPLS) and UNI interoperability among these different network architecture approaches Expected Output  Design guideline document (technical report) on this topic; not an Implementation Agreement Interaction with other forums and standards bodies  Close cooperation with IETF/CCAMP and ITU-T,Q14/SG15  MTNM Interaction with other OIF WG  Carrier, OAM&P, Interoperability Why the OIF?  Interworking and interoperability among different standardization bodies specifications and standards approaches is a key goal of the Optical Internetworking Forum

Project Timeline  Project Start: This meeting (Oct 2004)  Liaison to ITU and IETF describing project scope and soliciting interest: until next meeting  Solicit and receive contributions for 2 quarterly meetings  Baseline draft 2nd Quarter 2005  Proposed editor: Hans-Martin Foisel  Straw ballot 3rd quarter 2005  Principal ballot 1st quarter 2006

Motivation: Why Now?  Broad vendor and carrier support Strong request from the carrier and vendor members for interworking among network domains, which may use IETF or OIF/ITU-T standards and specifications.  Current activities at IETF CCAMP design teams could benefit from this document  This document will be based not only on available standards and specifications but also on first practical testing experiences
