Abstract

The Generalized Multi-Protocol Label Switching (GMPLS) suite of protocols has been defined to control different switching technologies as well as different applications. These include support for requesting Time Division Multiplexing (TDM) connections including Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) and Optical Transport Networks (OTNs).

Abstract

   The Generalized Multi-Protocol Label Switching (GMPLS) suite of
   protocols has been defined to control different switching
   technologies as well as different applications.  These include
   support for requesting Time Division Multiplexing (TDM) connections
   including Synchronous Optical Network (SONET)/Synchronous Digital
   Hierarchy (SDH) and Optical Transport Networks (OTNs).

   This document concentrates on the routing requirements placed on the
   GMPLS suite of protocols in order to support the capabilities and
   functionalities of an Automatically Switched Optical Network (ASON)
   as defined by the ITU-T.
