Motivation • Current situation: Legacy MPLS deployment for converged service • Evolution – GMPLS-based 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 of MPLS and GMPLS – Migration from MPLS to GMPLS (in Control plane) 61 st IETF Washington DC November 2004

Summary of I-D • Difference between MPLS and GMPLS wrt Interworking – Architecture (C/D 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 61 st IETF Washington DC November 2004

Remaining Issues • Document restructuring – Move Te-related stuff (4. 1. 2) to MRN 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) 61 st IETF Washington DC November 2004
