[openflowplugin-dev] Implementing en experimenter action

Michal Polkorab
Hi Shuva,
There is a wiki page regarding openflowjava extensibility here: https://wiki.opendaylight.org/view/Openflow_Protocol_Library:Openflow_Protocol_Library%27s_extensibility
I believe it might help you a lot.
Basically, in order to extend openflowjava you need to create identity for your action (in yang model). Then you have to create serializer and deserializer for your action. These classes must implement OFSerializer<Action> / OFDeserializer<Action>. Afterwards
you must get SwitchConnectionProvider instance (usually via ConfigSubsystem) and call registerAction(De)Serializer() method under correct key. Key examples can be found here: https://wiki.opendaylight.org/view/Openflow_Protocol_Library:Openflow_Protocol_Library%27s_extensibility:Registration_keys
(Code examples - look around OutputRegCodec class in openflowplugin)
Now you should be able to work with your experimenter action in openflowjava - you will probably need to extend openflowplugin too. You may find how in openflowplugin-extension-api project.
Regards,
Michal Polkorab
