Optimizing scalable video delivery through OpenFlow layer-based routing

Abstract
In recent years, HTTP Adaptive Streaming (HAS) is becoming the de facto standard for video delivery over the best effort Internet. In HAS, the video consists out of multiple temporal segments encoded at different quality rates. In this way, HAS allows to dynamically adapt the quality level to the perceived network conditions. Using Scalable Video Coding (SVC), the redundancy between these representations can be eliminated, increasing the efficiency of server and caching infrastructure. Software Defined Networking (SDN) allows the dynamic adjustment of forwarding tables to reroute different flows. Using a combination of the layered characteristics of SVC and the dynamic routing of flows, the delivery of video can be optimized. In this paper, an algorithm is presented to dynamically calculate the optimal delivery paths for the different video layers. This enables guaranteeing a reliable and continuous video playout. Using this approach the number of video freezes can be reduced with 72% compared to shortest path routing.
