  1. IP/MPLS - GMPLS interworking in support of IP/MPLS to GMPLS migrationdraft-oki-ccamp-gmpls-ip-interworking-05.txt Deborah Brungard: dbrungard@att.com Jean-Louis Le Roux: jeanlouis.leroux@francetelecom.com Eiji Oki: oki.eiji@lab.ntt.co.jp Dimitri Papadimitriou: dimitri.papadimitriou@alcatel.be Daisaku Shimazaki: shimazaki.daisaku@lab.ntt.co.jp Kohei Shiomoto: shiomoto.kohei@lab.ntt.co.jp 62nd IETF Minneapolis March 2005

  2. Motivation • Current situation: Legacy MPLS deployment for converged service • Evolution • GMPLS-based network for traffic demand • New features developed in GMPLS • Objective: Interwork between MPLS and GMPLS • Motivation • Coexistence ofMPLS and GMPLS • Migration from MPLS to GMPLS (in Control plane) 62nd IETF Minneapolis March 2005

  3. Summary of I-D • Difference between MPLS and GMPLS wrt Interworking • Architecture (C/D separation, Bidirectional, P&R) • Routing (GMPLS-TE-Opaque-LSA) • Signaling (New objects, message) • Mechanisms(M-G-M) • Routing: TE link, FA, Segment stitching • Signaling: Nesting, Contiguous, Stitching • Discovery of GMPLS signaling capability 62nd IETF Minneapolis March 2005

  4. Remaining work from previous version • Move Te-related stuff (4.1.2) to MRN docs. (DONE) • Develop G-M-G, M-G/G-M mechanisms (NOT YET) • Define Interwork & Migration (NOT YET) • Interwork: coexistence MPLS and GMPLS, MRN is referred for TE mechanism. • Migration: Converge to GMPLS-based networks 62nd IETF Minneapolis March 2005

  5. Remaining work to next version • Address both Integrated (Peer) and Augmented/Overlay models. • Merge the following ID • GMPLS Deployment in Existing IP/MPLS networks <draft-ali-ccamp-gmpls-deployment-augmented-model-00.txt> Feb 2005 62nd IETF Minneapolis March 2005

  6. Next Actions • Adopt as WG document • Requests for review/feedback 62nd IETF Minneapolis March 2005
