                             Extensions to
       the Path Computation Element Communication Protocol (PCEP)
    for Point-to-Multipoint Traffic Engineering Label Switched Paths

                     draft-palleti-pce-rfc6006bis-01

Abstract

   Point-to-point Multiprotocol Label Switching (MPLS) and Generalized
   MPLS (GMPLS) Traffic Engineering Label Switched Paths (TE LSPs) may
   be established using signaling techniques, but their paths may first
   need to be determined.  The Path Computation Element (PCE) has been
   identified as an appropriate technology for the determination of the
   paths of point-to-multipoint (P2MP) TE LSPs.

   This document describes extensions to the PCE communication Protocol
   (PCEP) to handle requests and responses for the computation of paths
   for P2MP TE LSPs.

   This document obsoletes RFC 6006.
