Lighty-openflow (io.lighty.modules)
is Lighty's version of openflow plugin.
- Add maven dependency in your pom.xml file.
<dependency>
<groupId>io.lighty.modules</groupId>
<artifactId>lighty-openflow-sb</artifactId>
<version>9.2.1-SNAPSHOT</version>
</dependency>
- Initialize and start LightyController. We have to add additional model paths to LightyController configuration that are used by other modules we are going to start. We will use Community-Restconf and Lighty-OFP in this example, so we need to add their model paths to controller configuration.
// initialize and start Lighty controller (MD-SAL, Controller, YangTools, Akka)
ArrayList<String> models = new ArrayList<>();
models.addAll(RestConfConfigUtils.MAVEN_MODEL_PATHS);
models.addAll(OpenflowConfigUtils.OFP_MAVEN_MODEL_PATHS);
ControllerConfiguration singleNodeConfiguration =
ControllerConfigUtils.getDefaultSingleNodeConfiguration(models);
LightyControllerBuilder lightyControllerBuilder = new LightyControllerBuilder();
LightyController lightyController = lightyControllerBuilder.from(singleNodeConfiguration).build();
lightyController.start();
- Initialize and start Openflow SouthBound plugin using services from LightyController.
LOG.info("Starting openflow...");
OpenflowSouthboundPluginBuilder opfBuilder = new OpenflowSouthboundPluginBuilder();
opfBuilder.from(
new OpenflowpluginConfiguration(),
lightyController.getServices()
);
ofplugin = opfBuilder.build();
ListenableFuture<Boolean> ofpStarted = ofplugin.start();
ofpStarted.get();
LOG.info("Openflow started");
- After executing code from previous steps all should be set and running. Openflow SouthBound plugin is now ready to use.
If openflow-plugin is running you can connect example switches with mininet.
sudo mn --controller=remote,ip=<IP_OF_RUNNING_LIGHTY> --topo=tree,1 --switch ovsk,protocols=OpenFlow13
Clustering depends on configuration of underlying akka actor system. Openflowplugin itself does not have independent settings for clustering.
Example application can be found under lighty-examples project.
