Hi all, I'm doing a project about DDos detection on SDN with Ryu. So I have a problem that I can not know the right moment when there are exactly 50 new packets coming to switch via openflow stats request from Ryu Controller.
If we don't know that moment, is there any solution for me to know the order of that 50 packets. I want to count packets match each flow entry in flow table every new 50 or 100 packets coming to switch to calculate entropy of IP dst, IP src. Does someone give me a solution? Thanks.
