• This Project Proposes to Build Vendor/Service agnostic config management platform which will enable the current ONAP

Platform to support config versioning, backup and config restoration features by leveraging underlying Controller platform.

Use Case-2

As a Network Operation Engineer, I want to modify initial configuration which was triggered via Controller as the previous configuration which was triggered is not accurate.

I want source which can provide me an interface to modify configuration by retrieving the specific vnf configuration from SDN-C and allow me to modify configuration on UI and trigger back to SDN-C.

design time and provide a specific QoS policy to Network controller during execution based on customer requirements that it

gets from MSO.
