Integration of ALTO and SDN protocols for peer to peer applications

Software Defined Networking (SDN) is a recently emerged network architec- ture by decoupling the control and forwarding planes of computer networks. This seperation enables to develop specific network operations by considering the requ- ierement of the applications running over the network. In general, this thesis aims to improve the performance of video streaming applications running over SDN. For this purpose first, four different route selection methods are proposed to increase the quality of experience (QoE) received by clients using Dynamic Adaptive Video Streaming over HTTP (DASH) running over SDN. Secondly, a video-on-demand (VoD) system architecture based on SDN and Application Layer Traffic Optimi- zation (ALTO) protocol interoperability is proposed. By using the proposed VoD architecture, two different methods are proposed for both the suitable video server and streaming route selection. Simulation results show that video streaming appli- cations running over SDN have better performance when compared to traditional video streaming applications.
