Dear Russ Housley,
RFC5317 said:" a single OAM technology for LSPs, PWs, and a deeply nested network". it means LSA OAM and PW OAM should be same, it means the OAM solution should be apply on both LSP and PW layer. From RFC5317 will not educe to one solution standard for mpls-tp oam conclusion.
B.R.

I support publication of this draft, although the SONET discussion could be discarded. Also, I would like to see a reference to RFC 5921 in the introduction.
RFC 5317 calls for one, and only one, protocol solution. At least that is how I read JWT Agreement. The most relevant text seems to be in Section 9:
They stated that in their view, it is technically feasible that the
existing MPLS architecture can be extended to meet the requirements
of a Transport profile, and that the architecture allows for a single
OAM technology for LSPs, PWs, and a deeply nested network.
Since the publication of RFC 5317, the MPLS WG consensus continues to be that only one OAM solution should become a standard.
