DCAE

Data Collection Diagram

Option 1 - RCC/VES Mapper

If the notification data is received from domain controller in non-VES format, such as, TAPI, and/or other JSON format, RCC is the data collection micro-service and VES Mapper micro-service is needed to convert the alarm notification into VES format.

RestConf Collector (RCC)

In MDONS use case, prior to subscribing to topics to get event notifications. We manually register 'DCAE' in the domain controller (DC). Once registration is successful, system can subscribe to different topics of DC to get event notification. It is mandatory to pass 'notification URL' to DC so that when event occurs it posts notification to that URL.

Option 2 - VES Colloctor

In case the domain controller acts like a VES client that can deliver the notification data in VES format,  VES collector micro-service is needed and VES mapper could be skipped in the data collection flow in MDONS closed instance.
