Purpose For information
Attachments (None)
We would like to inform you of the progress of three documents related to

"MPLS Transport Profile (MPLS-TP) Linear Protection to Match the Operational
Expectations of SDH, OTN and Ethernet Transport Network Operators"
draft-ietf-mpls-tp-psc-itu This document was
today approved by the IESG for publication as an IETF Standards Track RFC. The
document will now be passed to the RFC Editor for format and editorial work as
normal, and the RFC will be published in the normal course of events. From now
on, the only changes to the document should be editorial with no changes to the
technical content.

"Pre-standard Linear Protection Switching in MPLS-TP"
The IESG has reviewed this document for potential conflict with existing IETF
work and concluded that they do not object to its publication. Since this
document is being published on the Independent Stream its future progress
depends on work between the authors and the Independent Stream Editor (ISE).
The ISE can be contacted at

"Updates to MPLS Transport Profile Linear Protection"
This document is currently in IETF last call. Comments and discussions can be
tracked and contributed to via the MPLS mailing list or the general IETF
discussion mailing list. Last call is scheduled to complete on 9th April. It is
anticipated that last call will result in the need for minor updates to the
document before IESG review and approval.

We will be happy to answer any questions you have about IETF process for these

Best regards,
Adrian Farrel and Alia Atlas
