Stateful Path Computation Element (PCE) Protocol Extensions for Usage with Point-to-Multipoint TE Label Switched Paths (LSPs)
draft-ietf-pce-stateful-pce-p2mp-13
Technical Summary
The Path Computation Element (PCE) has been identified as an
appropriate technology for the determination of the paths of
point-to-multipoint (P2MP) TE Label Switched Paths (LSPs).
This document provides extensions required for Path Computation
Element Communication Protocol (PCEP) so as to enable the usage
of a stateful PCE capability in supporting P2MP TE LSPs.
Working Group Summary
The working group process has been uneventful. The author team
comes from vendors and operators who ship and deploy P2MP
RSVP-TE and so have a very strong interest in these PCE
extensions.
Document Quality
This document received only moderate review during its time in
the working group. P2MP function is somewhat fringe, and so
only a small group of people worked on it. As a result, WG last
call was quiet.
The document shepherd (Adrian Farrel) and the out-going chair
(Jon Hardwick) made detailed reviews that led to a number of
minor changes.
Implementation status is not known, but it is believed that
two vendors have roadmap plans.
