Framework for IP/MPLS-GMPLS interworking in support of IP/MPLS to GMPLS migration
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. An appropriate migration strategy can be selected based on various factors including the service provider's network deployment plan, customer demand, available network equipment implementation, operational policy, etc.
