This document describes extensions to Multi-Protocol Label Switching (MPLS) Resource ReserVation Protocol - Traffic Engineering (RSVP-TE) signaling required to support Generalized MPLS. Generalized MPLS extends the MPLS control plane to encompass time-division (e.g.@ Synchronous Optical Network and Synchronous Digital Hierarchy@ SONET/SDH)@ wavelength (optical lambdas) and spatial switching (e.g.@ incoming port or fiber to outgoing port or fiber). This document presents a RSVP-TE specific description of the extensions. A generic functional description can be found in separate documents.
