Comparative Analysis of Video Streaming in Software Defined Networking

Video streaming is the enlarged internet traffic and is becoming the most favorite content delivery mechanism for media services. Multiple video streaming will lead to degrading performance and impacting the user's Quality of Experience (QoE). Software-Defined Networking (SDN) is an architecture designed to create a network easier to manage and more flexible by abstracting the control plane from the data forwarding function in distinct networking devices. This paper mainly focuses on the traffic rerouting approach to improve video streaming bitrates and to reduce packet loss on the proposed enhanced video streaming framework. The experimental results affect and benefit of the proposed method using the Mininet emulated the OpenFlow network. It uses OpenFlow features to get traffic statistics from network devices and least cost path rerouting instead of default routing in the controller. The analysis results of traffic rerouting can be effectively applied in the network when the network congested conditions occurred and it should be carefully interpreted considering between the clients for enhancing video streaming.
