RFC 4208: Generalized Multiprotocol Label Switching (GMPLS) User-Network Interface (UNI): Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) Support for the Overlay Model, G. Swallow, J. Drake, H. Ishimatsu, Y. Rekhter2005-10-01T23:00:00-00:00Generalized 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. [STANDARDS-TRACK]
