Brian: Well, we do have the answer that we worked out in our first batch of RFCs, which is that the ANI with BRSKI, ACP and GRASP provides not only the secure autonomously established communications fabrics for ASA to talk to each other, but also that "SDN controller/orchestrars" can use the ANI to monitor/provision the network reliably and automatically secured. That monitoring/provisioning would IMHO simply leverage all existing YANG models and one of the various transports - netconf/ssh/tls and/or any alternative to that.
What i think is the small incompleteness to that story are the bits and pieces that draft-eckert-anima-services-dns-autoconfig and draft-eckert-anima-grasp-dnssd provide. Namely that all ANI devices would discover and autoconfigure themselves for those components that otherwise can not easily be provisioned with a chicken&egg problem: time (NTP), authentication (radius/diameter), logging - to name the most important ones. Now, when it comes to: "If we would start to define useful decentralised ASA that operate without a central SDN component - how would the GRASP protocols between them best look like ?" I think that's wide open, because there is not much established tradition for such decentralized ASA and their communication patterns. It is IMHO after IETF119 ANIMA meeting not even clear if there is an overwhelming desire to make such "east-west" communications (as i like to call it) utilize YANG to model the data - as opposed to CDDL. Check out the recording of the ANIMA session, i think we had a very good discussion on that topic. Is my answer missing an aspect you wanted to raise ?
