   The ability to compute paths for constrained point-to-multipoint
   (P2MP) Traffic Engineering Label Switched Paths (TE LSPs) across
   multiple domains has been identified as a key requirement for the
   deployment of P2MP services in MPLS and GMPLS networks.  The Path
   Computation Element (PCE) has been recognized as an appropriate
   technology for the determination of inter-domain paths of P2MP TE

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