Re: [PWE3] PWE3 WG adoption of draft-zhang-mpls-tp-pw-oam-config-06

I actually am closer to Tom on this issue,
but didn't see any reason to fight windmills on this one.

But was surprised at both clauses of your statement.

First, from a pure security PoV, all the management systems I have seen are more trustworthy than most control planes.
And since this is for TP which doesn't even assume an IP forwarding plane let alone IPsec,
then I have to assume that someone is going to start configuring everything using GACh payloads,
which frankly scares me, unless you have armed guards physically viewing all of your network elements.
(You may recall my rants on the lack of any security in MPLS and my futile attempts at pwsec
a few years back.)

Second, "OAM is about trust". Well yes, it is about how much the client layer trusts the server layer
or the customer trusts the service provider, or the boxes trust the fibers.
Or in many cases how little trust there is and how to check up so that you can prove your case of SLA noncompliance.
In any case I don't see the connection between this kind of "trust"
and the kind I think you are talking about in comparing control and management planes.

I trust that you will explain.

IMO I prefer the trust model of using the CP to set this up and coordinate the end points, and OAM is about trust.

so I support adoption of the draft, it is a move in the right direction
