LS293 - Request for G-ACh channel codepoint to support traditional transport environment

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.
