Architecture for Jakarta Release:
A1 Policy components (subset of 'Non-RealTime RIC'):
- A1 Policy Management Service (In ONAP CCSDK/SDNC)
- SDNC A1 Adapter (In ONAP CCSDK/SDNC)
- Near-RT RIC / A1 Simulator (in O-RAN Source Community (OSC)) (Wiki)
- A1 Policy Management GUI / NONRTRIC Dashboard (in O-RAN Source Community (OSC)) (Wiki)
The Gerrit Repos for codesource code is available in: ONAP CCSDK (O-RAN) Gerrit repo, with support functions available in OSC repos: OSC A1-Simulator (Gerrit) & OSC NONRTRIC Control Panel (Gerrit)
Additional Non-RealTime RIC functions are developed in the OSC NONRTRIC project - which reuses these A1 Policy components.
ONAP A1 Policy Management Service (ONAP CCDSK)
...
- Unified REST API for managing A1 Policies in all near-RT-RICs.
- A DMaaP API for A1 Policy management.
- Synchronized view of A1 Policy instances for each R-APP
- Synchronized view of A1 Policy instances in each near-RT-RIC
- Synchronized view of A1 Policy types supported by each near-RT-RIC
- Lookup service to find the near-RT-RIC to control resources in the RAN as defined in O1 (e.g. which near-RT-RIC should be accessed to control a certain CU or DU, which in turn controls a certain cell).
- Monitors all near-RT-RICs and maintains data consistency – e.g. recovery from near-RT-RIC restarts
- Support for different Southbound APIs to the near-RT-RICs (different versions of the A1-P and other similar APIs).
- HTTPS can be configured to use a supplied certificate/private key and to validate peers towards a list of trusted CAs/certs.
...
- HTTP proxy support for tunneling HTTP/HTTPS
...
- connections.
ONAP A1 Adapter (part of ONAP CCSDK/SDNC):
...
- Implemented as OSGI Feature/Bundles
- A1 Rest REST southbound
- NETCONF YANG Northbound
- RESTCONF > NETCONF adapter
- Mapping logic / Provider
- Can be included in an any SDNC/CCSDK persona
...
- View and Manage A1 policies in the RAN (near-RT-RICs)
- Interacts with the Policy Management Services NBI (REST API)
- Graphical A1 policy creation/editing is model-driven, based on policy type’s JSON schema
- Frontend: Angular framework
- Backend Java Springboot application
- Please refer to the OSC NONRTRIC Dashboard Control Panel Documentation (Latest)
OSC Near-RT RIC Simulator / A1 Simulator:
...
- Used to create multiple stateful A1 providers (simulated near-RT-RICs)
- Implemented as a Java Springboot application
- Swagger-based northbound interface, so easy to change the A1 profile exposed
- Please refer to the OSC A1 Simulator Documentation (Latest)
