The migration from Multiprotocol Label Switching (MPLS) Traffic
Engineering (TE) to Generalized MPLS (GMPLS) is the process of
evolving an MPLS-TE control plane to a GMPLS control plane.  An
appropriate migration strategy will be selected based on various
factors including the service provider's network deployment plan,
customer demand, and operational policy.

This document presents several migration models and strategies for
migrating from MPLS-TE to GMPLS.  In the course of migration, MPLS-TE
and GMPLS devices, or networks, may coexist that may require
interworking between MPLS-TE and GMPLS protocols.  Aspects of the
required interworking are discussed as it will influence the choice
of a migration strategy.  This framework document provides a migration
toolkit to aid the operator in selection of an appropriate strategy.

This framework document also lists a set of solutions that may aid in
interworking, and highlights a set of potential issues.  This memo provides information for the Internet community.

This document is a product of the Common Control and Measurement Plane Working Group of the IETF.
