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.
