Re: [nmrg] I-D Action: draft-irtf-nmrg-autonomic-sla-violation-detection-09.txt

Hello Brian,

Just to add to Jeferson’s response, to your comment re: whether there is applicability of ANIMA.  This is clearly specified in the draft in several places, e.g. section 5 top of page 9: “The provisioning of the P2P overlay should be transparent for the
   network administrator.  An Autonomic Control Plane such as defined in
   [I-D.anima-autonomic-control-plane<https://tools.ietf.org/html/draft-irtf-nmrg-autonomic-sla-violation-detection-09#ref-I-D.anima-autonomic-control-plane>] provides an ideal candidate for
   the P2P overlay to run on.”

In other words, this is clearly a decentralized autonomic application which requires a secure overlay for nodes (Autonomic Service Agents, in RFC 7575 parlance – come to think of it, we should add a reference to RFC 7575) to communicate with one another that could run on top of the ANIMA ACP. Really, very complementary.

Thanks

Could the authors clarify what they mean by Autonomous System?
Is this intended in the precise sense of a BGP4 AS or in a more
general way?

Yes, AS in the I-D can be read as a BGP AS. In any case, we are just describing a active measurement model at this point.

This is important for the applicability of the ANIMA solutions to
this use case, since it is hard to imagine an ANIMA Autonomic Control
Plane extending beyond a single BGP4 AS, and certainly not beyond
a single administrative domain.

Agreed, but the solution described in our I-D considers cooperative peers. Thus, it is safe to say that it targets single administrative domains which means that the ACP could be used.

Have the authors already studied the applicability of the ANIMA
solutions?

We did not study the applicability of ANIMA solutions for this I-D, but we have plans to do in a new one if a new ANIMA charter allow such possibility.

Best.
