O1 Component Architecture
According to the O-RAN-OAM-interface specification (O1) each MnS Provider (ME) implements a (TLS/)NetConf interface for Configuration Management and consumes TLS/HTTP-POST messages with a json body in VES message format.
The method for the VES subscription/un-subscription must be performed via NetConf, because VES itself does not provide such function. The MnS Consumer will use the NetConf interface for such an operation.
