Towards QoS-enabled SDN networks

SDN networks have become increasingly popular, especially for real time systems. Optimizing the self-defined network cost and performance is thereby primordial. This requires the network to meet real-time requirements and provide guarantees related to bandwidth and packet loss, and associated with the end-to-end delay and jitter which are essential indicators of QoS. This paper is an effort towards QoS-enabled SDN networks that allows establishing the formulation for both delay and jitter. Furthermore, we evaluate the effect of end-to-end delay and jitter in SDN networks as QoS metrics to finally establish their respective behavior.
