Hi Murphy McCauley, Thank your for your reply. As for the questions, 1) Yes, I am dealing with multiple openvswitches indeed, 2) Yes, they aren't getting to their intended destination. All the flow entries for each openvswitch are added simultaneously when the first packet of a flow is detected, and I want to use "*self.send_openflow(dpid, bufid, buf, openflow.OFPP_TABLE, inport)*" to send this first packet out from the openvswitch which reports this packet.
