# ONAP RAN-SIM
# Introduction :
RAN-SIM is a Radio Access Network Simulator, it is used to simulate the various functionalities of an eNodeB.
# Compilation Steps :
RAN-SIM can be compiled with `mvn clean install`. By default it executes:
- the standard unit tests
- the Spring integration tests
- BUT *does not build the docker images*
You can disable the integration tests by executing: `mvn clean install -DskipTests=true -Dmaven.test.skip=true`
# Building Docker images :
You can build docker images by executing profile "docker": `mvn clean install -P docker`
# Running RAN-SIM :
- After successful build navigate to 'ran-simulator/ransim/docker' directory.
- Use docker-compose up -d to start RAN-SIM
- Access the GUI using the following url in the web browser: 'http://<yourIP>:8081/ransimui'
# Logging :
- Login to ransim pod and you can get the logs from /opt/app/policy/servers/ransim/logs/ransim-rest.log
# Configuration :
The following capabilities can be modified in the 'ransim.properties' file based on user capabilities and configurations.
File directory:
ran-simulator/ransim/ransimctrlr/packages/base/src/files/install/servers/ransim/bin/ransim.properties
a) serverIdPrefix: Netconf server common prefix (use default value present in the file)
b) numberOfCellsPerNCServer: Maximum number of cells that can be handled in a single netconf server(use default value present in the file).
c) numberOfProcessPerMc:
Maximum number of netconf servers that can run in a single machine(use default value present in the file, which is for a machine of 8 GB RAM)
(A single netconf server uses approximately 350MB).
d) numberOfMachines:
Maximum number of machines available(use default value present in the file).
e) GridSize: (Applicable only for HONEYCOMB representation)
The number of cells that can be accommodated along one side of the cluster for an auto-generated layout.
However, it has no relevance now, as the initial layout is generated from a file. So use default value as 1.
f) strictValidateRansimAgentsAvailability:
A boolean value to check if any RAN-Sim agents are running (use default value present in the file).
g) sdnrServerIp:
SDNR IP address
h) sdnrServerPort:
SDNR port number
i) sdnrServerUserid:
SDNR user ID
j) sdnrServerPassword:
SDNR user password
k) maxPciValueAllowed:
maximum value of the physical cell Id. (Default is 503).
l)dumpFileName
Location of the dumpfile to load the topology.
The dump file is loaded from 'ran-simulator/ransim/docker/config'. A sample dump file - 'sample.json' contains deatils of 1000 cells.
For the controller to access the dump file from the the above location use the path - /tmp/ransim-install/config/sample.json
