Title : Considerations of point-to-multipoint route
optimization using PCEMP
Author(s) : J. Choi, et al.
Filename : draft-choi-pce-p2mp-framework-01.txt
Pages : 22

This draft describes the basic concepts of point-to-multipoint
(p2mp) path computation on the basis of the Path Computation Element
Metric Protocol (PCEMP). PCEMP, being soft-memory based, has the
capability of dynamic configuration of its finite state machines
(FSMs) in the participating PCEMP peers, and thus can support a
wide variety of traffic engineering techniques that are needed to
guarantee bandwidth demand and scalable fast protection and
restoration in PCE based p2mp frameworks. To take advantage of
bandwidth considerations and fast restoration mechanisms, the
centralized Controller, which is the key element in a PCE node,
is used for path computation in case of p2mp paths and can be used
in a scenario where reliable multicasting of bandwidth-on-demand
services becomes an important criteria for multiple-domain and/or
inter-domain PCE based architectures.

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
