Abstract
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.
