The Path Computation Element (PCE) defined in [RFC4655] is an entity that is capable of computing a network path or route based on a network graph, and applying computational constraints. A Path Computation Client (PCC) may make requests to a PCE for paths to be computed.

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


   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.
