Re: [Ryu-devel] Some question about how manage packet_in

Hi Luca, That is because as you have a flow rule installed (in the switch) already for that flow, the switch know already what to do (forward to the host), then no Packet-In (for rule´s instalation) is necessary. These are SDN/OpenFlow basic concepts. Regards, -- Túlio Albuquerque Pascoal

and have a ideia of how many flow rules your switch can support. By the way, are you working mainly about flow rule limitations? If so, please contact me by e-mail If you desire as it is part of my master thesis. Best Regards, Túlio Pascoal Em 15 de fev de 2017 10:01, "Moh'd R
