Multicast services are increasingly in demand for high-capacity applications such as multicast VPNs, IPTV (which may be on-demand or streamed), and content-rich media distribution (for example, software distribution, financial streaming, or database replication). The ability to compute constrained Traffic Engineering Label Switched Paths (TE LSPs) for point-to-multipoint (P2MP) LSPs in MPLS and GMPLS networks across multiple domains is therefore required.

                PCE-Based Computation Procedure to Compute       Shortest Constrained Point-to-Multipoint (P2MP) Inter-Domain                 Traffic Engineering Label Switched Paths


   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-controlled networks.    The Path Computation Element (PCE) has been recognized as an    appropriate technology for the determination of inter-domain paths of    P2MP TE LSPs.

   This document describes an experiment to provide procedures and    extensions to the PCE Communication Protocol (PCEP) for the    computation of inter-domain paths for P2MP TE LSPs.
