Can someone explain me (or send to link > with such explanation) how exactly ML2 plugin which is working on > neutron server is communicating with compute hosts with openvswitch > agents? Maybe this will set you on your way: ml2/plugin.py:Ml2Plugin.update_port uses _notify_port_updated, which then uses ml2/rpc.py:AgentNotifierApi.port_update, which makes an RPC call with the topic stated in that file. When the message is received by the OVS agent, it calls: neutron/plugins/openvswitch/agent/ovs_neutron_agent.py:OVSNeutronAgent.port_update. > I suppose that this is working with rabbitmq queues but I need > to add own function which will be called in this agent and I don't know > how to do that.
