An interesting read, and a really useful ACP application.
Comments/nits: can you expand ASBR, UPE and PE the first time they are used,
Move the digram from section 4 to section 3.
section 4 questions:
1) do the ANS message flow over the ACP? I assume so.
2) "The specific configuration command lines are
not in the scope of this document."
section 5:
objective-name = EX10
I think you want to do an IANA Action here to define your own?
EX10 is just... an example.
service-identification-type --- 3-bits. I don't think you need to be so
frugal in your use of bits. That could just be a CBOR Int.
path-identification-value, resource-type, same comment.
8. Security Considerations
It complies with GRASP security consideration.
You probably mean to say that it uses the security provided by the ACP.
I think that I'm missing some parts of the flow here.
I think that things would start with a NOC device ("SDN Controller")
sending out an M_DISCOVERY or M_FLOOD to discover the SPE node.
(Maybe it already knows, and if so, then how?)
This would have some kind of filter to say, "Answer if you are the resource
that is on edge of the AS and has a route to Network-Service-Initiator"
(which probably needs a label).
well, that might not be exactly the right thing, but the point being is that
these node*s* need to be found. There may be more than one!
Then the ANS communication would occur with that discovered node.
It would, as you say, negotiate the path.
I don't know [I-D.ietf-spring-segment-routing] or [I-D.ietf-mpls] that well,
but I didn't think that they included on-path (RSVP-like) discovery of route.
Probably, I've missed something.
Or do the P and PE node also need to respond and also be configured?
