Hi, Mininet uses Open vSwitch(OVS) as the default software switch to emulate the OpenFlow network. So OVS (NOT Mininet) generates the messages to send the controller. If your OVS already has the implementation for sending your own messages, you need to implement parser class in Ryu. If not yet, you also need to implement your own message into OVS, I think.
