SVC Videoconferencing Call Adaptation and Bandwidth Usage in SDN Networks

Abstract : Videoconferencing is a convenient way for meeting with people while avoiding transportation costs. With cameras now being a commodity feature on every laptop and smartphone, videoconferencing can be delivered by many software applications .However, live video streams have strong latency requirements and consume much bandwidth. Furthermore, videocon-ferencing is not efficiently implemented in current applications as it often relies on a central server and does not leverage network layer services. With the advent of Software Defined Networking, it is now possible to use advanced techniques such as multicasting and stream layering inside the network for optimizing live video call transmission. In this paper, we investigate the impact of these techniques on the bandwidth and latency of Scalable Video Coding videoconference calls. We also evaluate the call capacity of software defined networks using such techniques.
