The use of interactive media applications is becoming more common. With the current advancements in technologies, applications are becoming more advanced and research is being performed into adding more modalities to these applications to enrich the experience and increase their capabilities and uses. he performance of these applications depends heavily on the network resources available to them. Through the use of congestion control algorithms, these applications are able to get a fair share of the available bandwidth. However, congestion control algorithms are unable to minimize the delay caused by competing traffic. By combining the capabilities of OpenFlow with a priority queueing setup, we showed that we can provide low latency to a subset of flows. To control the utilization of the network resources and the effect the prioritization has on best-effort traffic, we use OpenFlow to control the bit rates of the high-priority flows. We show that by adjusting the ECN marking ratios of flows we are able to accurately control the bitrate of each of them.
