Abstract

Generalized Multiprotocol Label Switching (GMPLS) defines both routing and signaling protocols for the creation of Label Switched Paths (LSPs) in various switching technologies. These protocols can be used to support a number of deployment scenarios. This memo addresses the application of GMPLS to the overlay model.
