61st IETF Washington DC November 2004
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)

61st IETF Washington DC November 2004
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

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)
