Abstract

   The Generalized MultiProtocol Label Switching (GMPLS) suite of
   protocol specifications has been defined to provide support for
   different technologies as well as different applications.  These
   include support for requesting TDM connections based on Synchronous
   Optical NETwork/Synchronous Digital Hierarchy (SONET/SDH) as well as
   Optical Transport Networks (OTNs).

   This document concentrates on the signaling aspects of the GMPLS
   suite of protocols, specifically GMPLS signaling using Resource
   Reservation Protocol - Traffic Engineering (RSVP-TE).  It proposes
   additional extensions to these signaling protocols to support the
   capabilities of an ASON network.

   This document proposes appropriate extensions towards the resolution
   of additional requirements identified and communicated by the ITU-T
   Study Group 15 in support of ITU's ASON standardization effort.
