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.
