Dear Mr Justin! I followed your suggestion and can set the qos for each flow but completely on openflow switch. Now I want to periodically change the rate provide to each queue. I mean if I have a program that can calculate the best rate providing to each queue and base on that program result I want to change the rate set to each queue periodically (e.g time interval = 5 mins). I intend to implement it in FlowVisor. So, is it possible to control the queue rate of openvswitch from FlowVisor? Could you suggest me the part in openvswitch that I can send the command from outside to control?
