High-Level Overview: SDNR DMaaP Listener and RPC/DG Execution
This document captures the high-level design implemented for the OOFPCI POC use case and SDNR DMaaP Listener/Consumer and RPC/DG execution (based on the contents of the DMAAP message received).
To support closed-loop-automation use cases, such as SON, SDNR:
Receives DMAAP message from pertinent ONAP components (such as, Policy/OOF) and micro-services (such as, SON MS)
Invokes corresponding RPC's/DG's that implement the logic to accomplish the requested action (such as, add neighbors to a cell, configure PCI value of a cell...)
Sends confirmation back to Policy and other components, about success or failure of the requested action
The below diagram depicts high-level design/architecture:
All technical details associated with creating DMAAP listener docker for SDNR are included here.
All technical details associated with Directed Graphs for YANG/RPC execution are included here.
Key Prerequisites and requirements:
YANG models that capture configuration tree and RPC's are defined
DMAAP message payloads are aligned with YANG models

Main class1: oofpciClient
Wraps SvcLogicService: Processing/executing "graphs" → returning Properties
Main class2: oofpciProvider
owns as attribute "oofpciClient" service
Registers oofpcipocApiService (RestconfAPI)
Processes RPC commands, using "oofpciClient"
Instance for both classes started as bean. oofpciProvider gets oofpciClient instance

Hi Herbert - just an fyi...You are referring to the consumer/provider code associated with Netconf Notification associated with nbr list change notification...we have merged the code; however, it is not yet part of oofpcipoc karaf feature....Thanks!
In oofpcipoc-consumer the onNbrlistChangeNotification() processes the "RAN Neighbor List change notification" and forwards to "http://sdnc.onap:8282/restconf/operations". Which service is behind "sdnc.onap:8282"?
