Tal,

What is the intent of this document? If it is merely to exchange
information between SDO's, that's fine. However, I think that you could
take this document a step further. You could use this document to frame
a conversation about which OAM capabilities the IETF should develop and
which they should avoid.

For example, in Section 3.2.4, you distinguish between a failure, a
fault and a defect. In a connection oriented-environment, like SONET,
where bandwidth is reserved even when it is not being used, it makes
sense to manage all three. It also makes sense for the OAM mechanism to
be built into the protocol, as they are in SONET.

However, it is possible that neither assumption is true for
statistically multiplexed, connectionless environments like IP or
Ethernet. If you want to broaden the scope of your document, you might
want to explore these issues.
