Dear RYU Team, Please let me share my observation. First of all please let me represent simple testing topology. OvS1(RYU)-------------OvS2. Iperf3 sever is running at OvS1 and Iperf3 client is running at OvS2. Then the wireless interface of OVS2 cannot transmit any packet after 30 minutes of Iperf connection. Then I test another scenario. OvS1-------OvS2 without RYU controller. Iperf3 server at OvS1 and Iperf3 client and Ovs2. In this case, OvS2 can send TCP packets to OvS1 for 24 hours during iperf3 connection. The main reason for running iperf3 for 24 hours is testing for reliablity. In those first two scenarios, I really do not understand why the interface of OVS2 cannot transmit data packet to OvS1 when RYU controller is installed at OvS1. This is why I rasise this question whether RYU controller and OvS can use in the same physical machine. IP address of OvS1 is 10.0.0.8 and IP address of OVS2 is 10.0.0.1. 10.0.0.8 is used as both control IP and data IP which means I use in-band scenario in my testing case.
