Technical Summary

   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.

Working Group Summary

   No controversy. Two proposals came out as individual submissions and got
   merged before moving to WG I-D.

Document Quality

   There are existing prototype implementations, but no plans to include the
   protocol in product. Hence experimental.
