Developer Guide¶
This document provides a quickstart for developers of the Non-RT RIC.
SDNC A1 Controller¶
Prerequisites¶
- Java development kit (JDK), version 8
- Maven dependency-management tool, version 3.4 or later
- Python, version 2
- Docker, version 19.03.1 or later
- Docker Compose, version 1.24.1 or later
Build and run¶
- Go to the northbound directory and run this command ::
- mvn clean install
This will build the project and create artifcats in maven repo
- Go to oam/installation directory and run this command ::
- mvn clean install -P docker
This will create the docker images required for sdnc
- After this step check for the docker images created by the maven build with this command ::
- docker images | grep sdnc
- Go to oam/installation/src/main/yaml and run this command ::
- docker-compose up -d sdnc
- This will create the docker containers with the sdnc image, you can check the status of the docker container using ::
- docker-compose logs -f sdnc
- The SDNC url to access the Northbound API,
- http://localhost:8282/apidoc/explorer/index.html

Policy Agent¶
The O-RAN NonRT RIC PolicyAgent provides a REST API for management of policices. It provides support for:
- Supervision of clients (R-APPs) to eliminate stray policies in case of failure
- Consistency monitoring of the SMO view of policies and the actual situation in the RICs
- Consistency monitoring of RIC capabilities (policy types)
- Policy configuration. This includes:
- One REST API towards all RICs in the network
- Query functions that can find all policies in a RIC, all policies owned by a service (R-APP), all policies of a type etc.
- Maps O1 resources (ManagedElement) as defined in O1 to the controlling RIC.
The PolicyAgent can be accessed over the REST API or through the DMaaP Interface. The REST API is documented in the
nonrtric/policy-agent/docs/api.yaml file. Please refer to the README file of PolicyAgent to know more about the API’s.
Near-RT RIC Simulator¶
Prerequisites¶
- Java development kit (JDK), version 8
- Maven dependency-management tool, version 3.4 or later
Build and run¶
- Go to the near-rt-ric-simulator/ directory and run this command::
- mvn clean install
- The docker image can be built using::
- docker build -t {desiredImageName} .
- The image can be run using the command::
- docker run -it -p {desiredPort}:8085 {desiredImageName}
The functions written in a1.py are the ones matching the requests listed in the A1 open api yaml file. The functions written in main.py are the ones used for development purpose.
Different error codes can be thrown back according to the yaml file. In order to simulate an error code, simply add the query ?code={desiredCodeNumber} at the end of the address in the curl request.
