The following UML diagram shows the xNF Update flow from updates in A&AI for RunTimeDB

In this flow, A&AI has determined that a xNF (PNF or VNF) has been removed or added to the network.

And so downstream dependent components need to update their information that a xNF has been removed/added.

In the case of RunTime, there would be a record for that xNF and it would be need to be removed/added

the basic mechanism of how this is done is reused (nothing new is introduced): A&AI publishes an notify event on DMaaP bus,

and RunTime (component) subscribes to that event and updates itself.

    DMaaP -> RunTimeDB : Subscription
	hnote over RunTimeDB : Updates xNF Update
