Loa. Scott and all,
One of the documents mentioned in the liaison deals with revision  of an ITU-T G.8113 that deals with linear protection of MPLS-TP LSPs.

This issue has some history in the MPLS WG:
1. IETF has published RFC 6378 as a Proposed Standard
2. Some  serious technical issues have been then found with this document, and as a consequence, RFC 7324 has been published (also as P) to fix these issues
3.In addition, RFC 7121 has been published to describe an alternative solution to RFC 6378  to make linear protection of LPs to macth expectations of the Telecom operators; this is also a PS document.

And, in addition, ITU-T has published G.8113 that also deals with linear protection of MPLS-TP LSPs.

Having so  many documents dealing with the same issue looks problematic tome in any case. And since ITU-T now plans to approve revisions to its own standard pertaining to linear protection of LSPs, it makes sense to ask for some clarifications, mainly if a revision process of, say. 7121 should be initiated to mact the changes in G.8113.

My 2c,
Sasha

Scott,

So maybe just a short response.

"Thanks for your liaison on the final approval of the MPLS-TP
Recommendations, this marks a step in the joint MPLS-TP project.

IETF have to date published 45 MPLS-TP RFC from 7 working groups and
independent document. IETF still have 11 active Internet Drafts.

We are looking forward to your support completing the MPLS-TP
project."

I think you can correct grammar and spelling and send it timely.

Working Group,

Please comment on this?
