ALTO-assisted CDN-based video streaming over SDN

Software-defined Networking (SDN) is a promising network architecture for future internet applications by seperating the control and data layer of computer networks. On the other hand, Application Layer Traffic Optimization (ALTO) protocol provides ISP-friendly communication by provisioning network related information to the applications. In this paper, we propose a method for selecting appropriate video server using SDN and ALTO in content distribution network (CDN) based video streaming systems. Simulation results show that with the proposed method, the quality of experience received by the clients in video streaming applications is increased and the communication cost between internet service providers is reduced.
