The migration from Multiprotocol Label Switching (MPLS) TrafficEngineering (TE) to Generalized MPLS (GMPLS) is the process ofevolving an MPLS-TE control plane to a GMPLS control plane. Anappropriate migration strategy will be selected based on variousfactors including the service provider's network deployment plan,customer demand, and operational policy. This document presentsseveral migration models and strategies for migrating from MPLS-TE toGMPLS. In the course of migration, MPLS-TE and GMPLS devices, ornetworks, may coexist which may require interworking between MPLS-TEand GMPLS protocols. Aspects of the interworking required arediscussed as it will influence the choice of a migration strategy.This framework document provides a migration toolkit to aid theoperator in selection of an appropriate strategy. This frameworkdocument also lists a set of solutions that may aid in interworking,and highlights a set of potential issues.
