Videoconferencing over OpenFlow Networks: An Optimization Framework for QoS Routing

Abstract : The recent emergence of OpenFlow, in the field of networks' control, marks a major evolution in networking. Indeed, Openflow comes up with a centralized control plane (real or virtual) and a remote control of the data plan, which enable network's evolution with unprecedented rapidity. This evolution, come, however, with new challenges and open issues. The data path portion still resides on networking devices, while high-level routing decisions are moved to a separate remote server, which may impact the QoS of the supported services. Particularly, there is a need to guarantee at least the QoS that was formally provided using older and classical distributed protocols. This paper focuses on an improvement of the traditional OpenFlow controllers by providing QoS Routing support for Videoconfer-encing over OpenFlow networks. The simulation results under Mininet clearly demonstrate the effectiveness of the proposed approach.
