Title : Extended RSVP-TE for Point-to-Multipoint LSP Tunnels

This document describes a solution for point-to-multipoint (P2MP)
Traffic Engineering (TE) which extends 'RSVP-TE: Extensions to RSVP
for LSP Tunnels', RFC 3209, and 'Generalized Multi-Protocol Label
Switching (GMPLS) Signaling Resource ReserVation Protocol-Traffic
Engineering (RSVP-TE) Extensions', RFC 3473, to support P2MP TE LSPs.
A P2MP TE LSP is established by setting up multiple standard point-
to-point (P2P) TE LSPs from a sender node and all the downstream
branch nodes along the P2P TE LSP to one of the leaf nodes of the
P2MP TE LSP. A branched LSP is associated with original trunk LSP by
newly defined Association object so that the P2MP LSP tunnel is
established over the P2MP path. Because only a single standard LSP
will be present on any given link along the P2MP LSP, the defined
approach realizes maximum compatibility with existing
implementations. The solution supports standard tree operations:
setup, graft/join, and prune/leave. As the (G)MPLS signaling is
used, the P2MP TE LSP can be built using any switching technology
supported by GMPLS. This includes non-packet technologies.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
