Upon receipt of a DMaaP message from PCI-Handler MS recommending PCI updates, handle it, and trigger SDN-R (if allowed by policy) for the relevant PCI changes. Foll. aspects to be covered as part of this:

(a) Subscribe to the new DMaaP topics - to post the message towards SDN-R to trigger the PCI changes, and to get the feedback after carrying out the proposed changes.

(b) Upon receipt of the DMaaP message from PCI-Handler MS with recommended PCI changes, check if the recommended changes can be implemented (presently, it will be a very simple/trivial check).

(c) Send a DMaaP message to SDN-R with the PCI changes recommended.

(d) Retain the state information until a feedback is received from SDN-R.

(e) Upon receipt of feedback from SDN-R regarding the implementation of the changes (success/failure), capture the info in the logs.

(b) and (c) are carried out in accordance with the Control loop definition for this use case.
