       Generalized Multiprotocol Label Switching (GMPLS) Ethernet
               Label Switching Architecture and Framework

Abstract

   There has been significant recent work in increasing the capabilities
   of Ethernet switches and Ethernet forwarding models.  As a
   consequence, the role of Ethernet is rapidly expanding into
   "transport networks" that previously were the domain of other
   technologies such as Synchronous Optical Network (SONET) /
   Synchronous Digital Hierarchy (SDH), Time-Division Multiplexing
   (TDM), and Asynchronous Transfer Mode (ATM).  This document defines
   an architecture and framework for a Generalized-MPLS-based control
   plane for Ethernet in this "transport network" capacity.  GMPLS has
   already been specified for similar technologies.  Some additional
   extensions to the GMPLS control plane are needed, and this document
   provides a framework for these extensions.
