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 for the comments. Answers below. Em seg, 26 de jun de 2017 às 21:12, Brian E Carpenter <brian.e.carpenter@gmail.com<mailto:brian.e.carpenter@gmail.com>> escreveu: Hi, > 7. Implementation Considerations > > The active measurement model assumes that a typical infrastructure will have multiple network segments and Autonomous Systems (ASs), and a reasonably large number of routers. 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. Regards Brian Carpenter Best.
