Abstract

   This document describes extensions to RSVP-TE signaling required to
   support Generalized MPLS.  Generalized MPLS extends MPLS to encompass
   time-division (e.g. SONET ADMs), wavelength (optical lambdas) and
   spatial switching (e.g. incoming port or fiber to outgoing port or
   fiber).  This document presents an RSVP-TE specific description of
   the extensions.  A CR-LDP specific description can be found in
   [GMPLS-LDP].  A generic functional description is presented in
   [GMPLS-SIG].
