OCNADD Services

Table 2-4 OCNADD Services

Services Descriptio
Admin Service The Admin Service administers the Kafka Cluster and it provides an interface to create and delete a Consumer Adapter deployment.
Aggregation Service The Aggregation Service collects and aggregates network traffic from multiple NFs (For example: SCP 1 and 2 and/or SEPP, NRF, 3rd party NF, and so on).
Alarm Service The OCNADD Alarm service is used to store the alarms generated by other OCNADD services.
UI Router Service The OCNADD UI Router service acts as an interface between the CNC Console and the OCNADD services.
Configuration Service The Configuration Service is used by the OCNADD UI service to configure 3rd party message feed.
Consumer Adapter Service The Consumer Adapter Service manages the third-party specific connection parameters and provide secure message transport towards the third-party consumer application.
Health Monitoring Service The Health Monitoring Service monitors the health of each OCNADD service and provides alerts related to the overall health of the OCNADD.
Kafka Broker Service The Kafka Broker Service stores the incoming network traffic from different NFs. It also stores the intermediate processed data from different microservices.
GUI service The GUI service is used as an interface between the CNC Console and OCNADD that provides the user interface to configure the Data Feeds.
Filter service The filter service filters the feed data as per configuration. The filtered feed is then used for preparing xDR reports or consumed by External Kafka Feeds.
Correlation service The correlation service creates xDR reports for the feed data as per configuration. The xDR reports are then consumed by External Kafka Feeds.
Redundancy Agent The Redundancy agent is responsible for syncing configurations and maintaining two-site redudancy between mated worker group pair.
