Abstract
The migration from Multiprotocol Label Switching (MPLS) to Generalized MPLS (GMPLS) is the process of evolving an MPLS traffic engineered (TE) control plane to a GMPLS control plane. In the course of migration, several interworking cases may exist where MPLS and GMPLS devices or networks must coexist. During the migration process, standard interworking functions are needed to allow graceful deployment of GMPLS technologies while keeping existing IP/MPLS networks unaffected.
