Performance Measurement Towards Enhance Video Streaming in Software Defined Network

Abstract

Video streaming is becoming the most popular content delivery mechanism for media services. Multiple video streams will compete for bandwidth, thus leading to degrade performance and impacting the received quality of experience (QoE). Software Defined Networking (SDN) provides a significant advantage because it is easier to introduce and tune up new functionalities. The logically-centralized control of OpenFlow brings to the operators the flexible and convenient controllability over the underlying networks. In this paper, it measures video streaming throughput among the different client groups and proposes the effective video streaming framework. It uses OpenFlow features to get traffic performance from network devices. That is showed the end to end throughput of streamed video traffic over Mininet emulated OpenFlow networks. The preliminary result shows the throughput of streamed videos at client and it should be carefully interpreted considering between the clients for enhance video streaming.
