Hi yusuke, Thanks fir the info however can you please specify how to implement the following scenario:
1. Iperf client send the tcp message on port 8000 2. Iperf server receives the tcp port through ovs 3. Ryu asks the ovs to write the flow with default values 4. If port numbe is greater than 5000, idle timeout is 100 seconds. This is what I want to implement. Can you please guide.
