The script version of the O-RU Fronthaul Recovery use case provides a python script that regularly polls DMaaP Message Router (MR) for "CUS Link Failure" messages.
When such a message appears with the "eventSeverity" set to anything but "NORMAL", a configuration change message with the "administrative-state" set to "UNLOCKED" will be sent to the O-DU mapped to the O-RU that sent the alarm.
When such a message appears with the "eventSeverity" set to "NORMAL" a printout will be made to signal that the alarm has been cleared, provided that the verbose option has been used when the test was started.
To run this script Python3 needs to be installed. To install the script's dependencies, run the following command from the app folder: pip install -r requirements.txt
Also, the MR needs to be up and running with a topic created for the alarms and there must be an endpoint for the configuration change event that will accept these.
The host names and the ports to the MR and SDNR services can be provided when the container is started if the default values are not correct. The topic can also be changed.
The mapping from O-RU ID to O-DU ID is specified in the file o-ru-to-o-du-map.txt. This can be replaced by providing a different file when starting the application.
For convenience, a message generator and a change event endpoint simulator are provided.
Go to the app/ folder and run python3 main.py. The script will start and run until stopped. Use the -h option to see the options available for the script.
Go to the app/ folder and run docker build -t oru-app ..
The container must be connected to the same network as the MR and SDNR are running in. Some of the parameters to the application can be provided with the -e PARAM_NAME=PARAM_VALUE notation. Start the container by using the command, with available params listed: docker run --network [NETWORK NAME] --name oru-app -e VERBOSE=on -e MR-HOST=[HOST NAME OF MR] -e MR-PORT=[PORT OF MR] -e SDNR-HOST=[HOST NAME OF SDNR] -e SDNR-PORT=[PORT OF SDNR] oru-app.
To build the image for the message generator, run the following command from the simulators folder: docker build -f Dockerfile-message-generator -t message-generator .
The message generator's container must be connected to the same network as the other components are running in. Some of the parameters to the application can be provided with the -e PARAM_NAME=PARAM_VALUE notation. Start the container by using the command, with available params listed: docker run --network [NETWORK NAME] --name message-generator -e MR-HOST=[HOST NAME OF MR] -e MR-PORT=[PORT OF MR] message-generator.
To build the image for the SDNR simulator, run the following command from the simulators folder: docker build -f Dockerfile-sdnr-sim -t sdnr-simulator .
The SDNR simulator's container must be connected to the same network as the the other components are running in. Some of the parameters to the application can be provided with the -e PARAM_NAME=PARAM_VALUE notation. Start the container by using the command, with available params listed: docker run --network [NETWORK NAME] --name sdnr-simulator -e MR-HOST=[HOST NAME OF MR] -e MR-PORT=[PORT OF MR] sdnr-simulator.
Go to the docker-compose/ folder and run bash start.sh, see control loop version.
This scripts will start up four components: dmaap-mr oru-app sdnr-simulator message-generator
