Hello Chris,

I think you have the order wrong.
The MPLS-TP OAM requirements are in RFC5860:
http://tools.ietf.org/html/rfc5860

draft-bhh-MPLS-TP-OAM-Y1731 is a solution based on RFC5860.

draft-bhh-MPLS-TP-OAM-Y1731 provides a set of tools that fits in
a larger toolbox with multiple tools.

The service provider can pick a selection of the tools for
use in his network by enabling the ones he needs.
CMCC and many other service providers have a preference for
the tools provided by draft-bhh-MPLS-TP-OAM-Y1731.

Best regards, Huub.
