  1. IP/MPLS - GMPLS interworking in support of IP/MPLS to GMPLS migrationdraft-oki-ccamp-gmpls-ip-interworking-04.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 61st IETF Washington DC November 2004

  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) 61st IETF Washington DC November 2004

  5. 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 61st IETF Washington DC November 2004

  6. Major Changes • Mechanism M-G-M scenario is refined. • G-M/M-G scenario is added. GMPLS-based NW MPLS NW MPLS NW G1 G3 G2 G5 G4 G6 MPLS NW GMPLS-based NW G1 G3 G2 G5 G4 G6 61st IETF Washington DC November 2004

  7. Remaining Issues • Document restructuring • Move Te-related stuff (4.1.2) to MRN docs. • Develop G-M-G, M-G/G-M mechanisms • Define Interwork & Migration • Interwork: coexistence MPLS and GMPLS, MRN is referred for TE mechanism. • Migration: Converge to GMPLS-based networks • Five Interworking scenarios • M-G-M (PSC, non PSC) • G-M-G (PSC, non PSC) • G-M/M-G (PSC) 61st IETF Washington DC November 2004

  8. Next Actions • Adopt as WG document • Requests for review/feedback 61st IETF Washington DC November 2004
