Primary Goals for Non-RealTime RAN Intelligent Controller (Non-RT RIC):
|
Overall objective for the D Release: In the D Release we focus mainly on continued improved and evolution for the O-RAN A1 interface, and providing some building blocks to support the emerging Non-RT-RIC Apps ("rApps") and R1 interface concepts from O-RAN. |
D Feature Scope:
|
...
Architecture for Release D:
...
Non-RT-RIC Control Panel
- Non-RT-RIC (Spring Cloud) Service Gateway
- Non-RT-RIC (Kong) Service Exposure Prototyping
- A1 Policy Management Service
- Enrichment Information Coordinator
- Initial Non-RT-RIC App Catalogue
- SDNC A1 Controller
- Near-RT RIC A1 Simulator
- Initial K8S Helm Chart LCM Manager
- Test Framework
- "Helloworld" O-RU Fronthaul Recovery use-case
The code base for "D" Release is in the NONRTRIC, NONRTRIC-ControlPanel, and A1-Simulator, source repositories (Gerrit) - D Branch
Non-RT-RIC Control Panel
Graphical user interface to interact with the NON-RT RIC services.
...
Please refer this developer guide to set up in your local environment. More information about Non-RT Ric RIC control panel can be found here.
Non-RT-RIC (Spring Cloud) Service Gateway
...
Spring cloud Gateway provides the library to build the API Gateway for Microservice Micro-service architecture. In Non-RT-RIC we build the basic API gateway using spring cloud gateway which then exposes two Non-RT RIC functions; Policy Management Service & Enrichment Coordinator Service. You can add predicates through code or yaml and in Nonrtric Non-RT-RIC we prefer to use yaml.
NONRTRIC gateway code can be found at:
- https://gerrit.o-ran-sc.org/r/gitweb?p=portal/nonrtric-controlpanel.git;a=tree;f=nonrtric-gateway;hb=refs/heads/masterdawn
More information on the Spring Cloud Gateway can be found in the documentation here.
...
The NONRTRIC Kubernetes deployment will deploy Kong if the installKong flag is set to true. During uninstallation of nonrtric components it will also remove kong Kong if it's deployed by nonrtric script.
If the ingress enabled flag is set to true then it will create the ingress objects for A1 policy Policy & Enrichment Service so the kong Kong gateway (acts as ingress controller) will expose these functions.
NONRTRIC Kubernetes deployment can be found at:

Kong installation done by Nonrtric nonrtric script is Without Database.

A1 Controller Service above A1 Adaptor that provides:
- Unified REST & DMAAP DMaaP APIs for managing A1 Policies in all near-RT-RICs
- Operations:
- Query A1 Policy Types in near-RT-RICs
- Create/Query/Update/Delete A1 Policy Instances in near-RT-RICs
- Query Status for A1 Policy Instances
- Maintains (persistent) cache of RAN’s A1 Policy information
- Support RAN-wide view of A1 Policy information
- Streamline A1 traffic
- Enable (optional) re-synchronization after inconsistencies / near-RT-RIC restarts
- Added support for multiple near-RT-RICs (& multi-version support)
- Unified REST & DMaaP NBI
- Converged ONAP & O-RAN-SC A1 Adapter/Controller functions in ONAP SDNC/CCSDK
- (Optionally deploy without A1 Adaptor to connect direct to near-RT-RICs)
Documentation about the service can be found at:
A1 Enrichment Information Job Coordination Service
...
Documentation about the service can be found at:
(Initial) Non-RT RIC APP catalog
...
- APPs can be registered / queried
- Limited functionality/integration for now
- A building block for coming releases as the R-APP concept matures
