Hi to all, I am using PoX controller and want to add few scripts for QoS routing, but for now I don't want to modify switches. I created script that reserves bandwidth for QoS flows by using Linux HTB scheduling capability. But that is problematic because flows with low bandwidth requirement experience higher delays. I am wondering if I somehow can extend this script to provide delay guarantees as well?
I have read one interesting paper about providing delay guarantees with OpenFlow by sending probe packets from controller to estimate delay on links, but there is no dedicated queues for sessions like in my case. Can u please give me few tips how to estimate how much bandwidth I should allocate for session not to exceed delay bounds (if there is some way)? Best Regards, Alex
