Technical Summary

  This document describes a method for generating an aggregated
   pseudowire status message on Multi-Protocol Label Switching (MPLS)
   network Label Switched Path (LSP).

   The method for transmitting the pseudowire (PW) status information is
   not new, however this protocol extension allows a Service Provider
   (SP) to reliably monitor the individual PW status while not
   overwhelming the network with multiple periodic status messages. This
   is achieved by sending a single cumulative summary status
   verification message for all the PWs grouped in the same LSP.

Working Group Summary

The working groups has been working on this for about five years. It
has discussed it a number of times and supports publication.
Document Quality

This is a well written document.

There has been industry interest but we are not sure how widely
it has been implemented. It is not uncommon in this area
for RFC to proceed before implementation.
