Body:
At the February meeting of ITU-T Study Group 15, we have reached the
conclusion that the needs of many of the operators participating in
this work are not met by the solutions currently under development in
the IETF. Therefore, we have decided to progress this work through
ITU-T Recommendations. We request that the IETF provide the necessary
G-ACh codepoint allocations to support this work through advancement of
draft-tsb-mpls-tp-ach-ptn. Note that we have done additional work
during this meeting to more clearly define the network environment for
this application and produced a scope of applicability in TD522/WP3
(attached). draft-tsb-mpls-tp-ach-ptn will be updated to include this
scope statement.
The use of this G-ACh code point will fully comply with the framework
and architecture for MPLS-TP that is currently being defined by IETF in
cooperation with ITU-T.  Allocation of this code point will allow ITU-T
to develop the tools required to address the unique needs of the
transport network and will make more efficient use of the resources of
both organizations.  Providing this codepoint will allow ITU-T to
satisfy the immediate needs expressed at the recent Study Group 15
meeting recognizing that it is very important for ITU-T and IETF to
provide timely solutions to maintain support for the MPLS-TP
agreements.

Attach: TD522/WP3 and C-1124 Appendix I.
