Technical Summary

This document specifies how signaling and selection processes for
Pseudowire (PW) Virtual Circuit Connectivity Verification (VCCV) are
modified to ensure backward compatibility and allow use of proactive
Connectivity Verification (CV), Continuity Check (CC), and Remote
Defect Indication (RDI) over MPLS Transport Profile (MPLS-TP) PWs.
This document introduces four new CV types and, to accommodate them,
a new VCCV Extended CV parameter for PW Interface Parameters Sub-TLV
is defined.

Working Group Summary

This was a straightforward document as far as the WG was concern. 
The majority of discussion of the draft occurred while it was an 
individual draft, when it went though several round of comments and 
revisions before being adopted as a WG draft.

Document Quality

There are no known implementations of the draft at this time. At least 
one vendor has it under consideration for implementation.
