Software Defined Networking (SDN) provides the ability to make any control related decisions centrally, which transforms legacy network devices to simple forwarding elements. In this new architecture the decisions are made from an application that acts as a strategic control point in the network and manages the flow control for improved network management and application performance. This paper aims at developing a novel SDN platform that monitors the network and makes changes in the paths to achieve better performance in the network in case of video streaming. More specifically, the developed SDN packet loss controller periodically monitors a networking parameter on the video packets transmission path and collects statistics, based on which, it performs network path selection. As a result, the Quality of Experience (QoE) for the end-users is increased, as compared to a standard SDN controller.
