Connection, decode it and sends it over the relevant SCTP. 參考

manager
(Submgr)
1. Handles RIC_SUB_REQ and RIC_SUB_RESP type RMR messages

7. Component Functions in Bronze Release
App manager
(Appmgr)
Provides a flexible and secure way for deploying and managing various RIC xApp applications in a
Kubernetes environment. 參考
Vespamgr
Uses the VES Agent to adapt near-RT RIC internal statistics’ collection using Prometheus to scrape
metrics from platform and xApp microservices and forward to ONAP or VES Collector via VES
interface (VNF event streaming). 參考
Alarmadaptor/Alarmmanager
The AlarmAdapter is responsible for managing alarm situations in RIC cluster and interfacing with
Northbound applications (e.g. Prometheus AlertManager) to post the alarms as alerts. 參考
Routing manager
(Rtmgr)
1. NorthBound Interface (__NBI__): Maintains the communication channels towards RIC
manager components
2. Routing Policy Engine (__RPE__): Provides the logic to calculate routing policies
3. Shared Data Layer (__SDL__): Provides access to different kind persistent data stores
4. SouthBound Interface (__SBI__): Maintains the communication channels towards RIC tenants
and control components
5. Control Logic (__RTMGR__): Controls the operation of above functions 參考

5. Updating RMR version to 4.5.2
10. Component Bronze v.s Cherry Release (Add or Update functions)
O1 mediator
1. Simple xApp configuration via pass-through yang models.
2. E2 states of connected gNBs
3. Alarm states (incl. xApps) from new alarm adapter
4. O1 Alarm events from new alarm adapter to Prometheus Alert Manager to VESPA via REST
to external VES collector 參考
5. rmr and xapp-frame version change
