Body
ITU-T Q9/15 wishes to provide the IETF MPLS WG an update on our progress on
the previously
liaised draft Amendment 1 to Recommendation ITU-T G.8131/Y.1382 (2014),
“Linear protection
switching for MPLS transport profile (MPLS-TP): Amendment 1”.

We have made two modifications to the previously liaised draft:

- We had previously stated that we would add a figure showing the full
structure of the APC
PDU to clause 8.1. We have since decided this is more appropriate to put in an
informative
appendix.

- The document currently indicates that trail protection for LSP sublayers is
supported but the
functional model is for further study. We have reached a conclusion on what
the functional
model should be, and intend to include that in the amendment.

The updated draft of this amendment is attached. We would appreciate any
comments you have on
this amendment in advance of our next meeting, which is 22 June-3 July 2015,
at which time we
intend to consent the amendment.

(for
Consent)”
