If your goal is scalability, I doubt that sending the first packet of every flow up to the controller is a good way to achieve it. Your network will scale better if you proactively install flows, reducing the need to send traffic to the controller. You didn't say what version of OpenFlow you had installed, but it may not make sense to use the OpenFlow reference implementation for scalability testing. I don't think it's designed for performance but rather for simplicity. _______________________________________________ openflow-discuss mailing list [email protected] https://mailman.stanford.edu/mailman/listinfo/openflow-discuss
