hello, Here the traffic passes through every ports in OVS on OFCTL will not route 100% in the routing table, as everyone knows. But , there is a possibility if the traffic is coming from Static NAT to local address, only one or two packets may route. And to resolve this apply the rules over the ports from the ryu itself that if the packets are in the waiting stage they should not attain transmit failure mode. In that case DDOS may be prevented, while the packet discarding doesn't matter due to those rules in Ryu-Controller.
