Don

A draft does not need to be complete for it to be
accepted as a WG draft, it needs to be a suitable
platform that the WG can use to move forward.

> IETF is extending MPLS technology all the time. The extensions 
that I see that are required are:

1) transport OAM enhancements

Given that the existing PWE3 OAM functions are adequate
for our own purposes, what is special about the transport
environment that requires extensions?

It is not appropriate to list alternative OAM protocols,
PWE3 needs to know what specific additional functionality
it needs to provide a comprehensive OAM design.

2) support for transport protection switching

PWE3 has already started work on protection. What
requirements exist in the transport network that are not
addressed by the proposed work?

Would you be prepared to contribute text to a PWE3 protection
requirements draft?

3) GMPLS - ASON control plane enhancements (using the procedures
that CCAMP has in place with ITU)

The control plane design for PWE3 over MPLS and for MPLS is
a proven design that is widely deployed. How is the existing
designs unsuitable, and what additional requirements does a
transport environment have that are not satisfied by that
design.
