Hello, I have just started working on open flow and I appreciate if you could possibly help me with your advice.
My project is about SDN and I should extend the Open-flow protocol in order to send a parameter (just a number) from controller to the switch do some calculation and return the result to the controller. I think there can be two ways to address this problem. Either by abusing the unused filed or making a new type of message. The controller is Ryu and switches are open virtual switch. I have made a message type which is send from Ryu controller to open virtual switch but the virtual switch does not recognize it because I do not know where I should parse the message in switch side. I do not know in which libraries in open flow or open virtual switch I should parse. Do you know how to extend the protocol to add a message type? If you decide to use the already existing field of openflow to send the parameter then which field do you recommend and how will you do this implementation ?
