Hello, Does the need to explicitly distinguish ANIMA work from HOMENET work still exist If not, then why not remove/forget about this possibly contentious terminology. (the goal would be to avoid unnecessary difficulties for ANIMA documents publication at IESG review or IETF last call stages).
FWIW, my understanding of "professionally managed" is "managed _BY_ a professional". Here the person or entity being the "professional" is providing a service (paid or free) to manage a given network as part of her job (or contract). In the mission of her job (or contract) the professional is "external" to the user of the network being managed (i.e. act as a first/third party). * note: a homenet can well be very professionally managed in the sense that it follows BCP but it does not mean it is managed by someone for which it is the job to do this (e.g. John Doe, who is a skilled engineer, manage its homenet for himself, or manage homenets for his friends/relatives...) ** note: a homenet can well be completely unmanaged, i.e. relying exclusively on full plug-and-play mechanisms.

If the SDN controller is configured by a NOC or an NMS database managed by the NOC, yes. I think we are talking about configured by a human in the NOC when we say "traditional" or "professional". > If the SDN controller uses the ACP, does this change the result ? No. But if the SDN controller is configured by an ASA, not by a human, it's autonomic. > Long term NMS'ler would say controller/orchestrator are just fancy new > words for mostly the provisioning part of NMS, but: > > Good controllers/orchestrator would also be intent based only that the > rendering of the intent would not necessarily be autonomic.

That's why the GRASP draft used to contain a riff about how routing algorithms were the original autonomic mechanisms. If you remember, we had to remove that to satisfy the Routing Area people. If ANIMA succeeds, we will have simply extended that original DARPA requirement.
