       Generalized MPLS (GMPLS) Support for Metro Ethernet Forum
                 and G.8011 Ethernet Service Switching

Abstract

   This document describes a method for controlling two specific types
   of Ethernet switching via Generalized Multi-Protocol Label Switching
   (GMPLS).  This document supports the types of switching corresponding
   to the Ethernet services that have been defined in the context of the
   Metro Ethernet Forum (MEF) and International Telecommunication Union
   (ITU) G.8011.  Specifically, switching in support of Ethernet private
   line and Ethernet virtual private line services are covered.  Support
   for MEF- and ITU-defined parameters is also covered.
