Introduction
This is considered as an extension of MDONS use case from ONAP Frankfurt release.
REQ-325
Business Value
Design & Implementation
The scope of code change will be very limited with the existing capability at ONAP CLAMP, DCAE and POLICY components. Given the fact that FNC Virtuora MSA support has already delivered
L0/L1 alarms and PM data in VES (CEDM) (7.0 version) format. However, those delivered through TAPI APIs are retrieved from FPM server and converted into TAPI standard in Json format.
