    Path Computation Element Communication Protocol Extensions for 
         Associated Bidirectional Label Switched Paths (LSPs)
               draft-barth-pce-association-bidir-00

Abstract

   The Path Computation Element Communication Protocol (PCEP) provides
   mechanisms for Path Computation Elements (PCEs) to perform path
   computations in response to Path Computation Clients (PCCs) requests.
    The stateful PCE extensions allow stateful control of Multi-Protocol
   Label Switching (MPLS) Traffic Engineering (TE) Label Switched Paths
   (LSPs) using PCEP.

   This document defines Path Computation Element Communication Protocol
   (PCEP) extensions for binding two reverse unidirectional RSVP-TE LSPs
   into an Associated Bidirectional Label Switched Path (LSP).
