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).

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.
