Modification of Routing and Signaling

The development of GMPLS requires the modification of current routing and signaling protocols. The adoption of a common, standardized control plane for managing packet/cell switches and optical switches is extremely important to the networking industry. This introduces a unified method for achieving fast provisioning, restoration, routing, monitoring, and managing data-switched and optical-switched networks while maintaining interoperability between multiple vendors. The MPLS control plane is being extended from controlling data switches to a more generic role of controlling any type of switching, including optical switching—hence the term Generalized MPLS.

To help MPLS span switches that are not packet-oriented, ...
