Route optimization for DASH over Software Defined Networks

In this paper, a method for the selection of the paths between the server and the clients for Dynamic Adaptive HTTP Streaming (DASH) over Software Defined Networks (SDN). In the proposed method, an optimization model is presented for increasing the Quality of Experience (QoE) in the clients by increasing the average received bitrates and for providing fairness by decreasing the difference between the bitrates received by the clients.

Simulation results show that, thanks to the SDN technology, the QoE achieved by the DASH clients is improved by assigning streaming paths according to the proposed model.
