The OAM architecture is defined by WG1 in the O-RAN OAM architecture document. WG2 clarified the function split between non-real-time-RIC and an Orchestrator FCAPS Framework. Please see the attached document.
Integration into ONAP
In the meeting from 2019-08-12 was clarified the expected integration of the OAM Architecture into ONAP.
The ONAP VES collectors will receive the VES messages of the O1 interface. For real-time event streaming the ONAP project provide HV-VES.
For NetConf interfacing with the different components, the functions of ONAP SDN-R will be used (subproject of SDNC and based on CCSDK)
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.
