      Generalized Multiprotocol Label Switching (GMPLS) Control of
        Ethernet Provider Backbone Traffic Engineering (PBB-TE)

Abstract

   This specification is complementary to the GMPLS Ethernet Label
   Switching Architecture and Framework and describes the technology-
   specific aspects of GMPLS control for Provider Backbone Bridge
   Traffic Engineering (PBB-TE).  The necessary GMPLS extensions and
   mechanisms are described to establish Ethernet PBB-TE point-to-point
   (P2P) and point-to-multipoint (P2MP) connections.  This document
   supports, but does not modify, the standard IEEE data plane.
