SDN-based adaptive routing for video streaming over HTTP

In this paper, we propose a bitrate adaptation algorithm at the client side in real time combined with a SDN-based dynamic path selection for HTTP-based video streaming. Experimental results show that the proposed method can provide users with better Quality of Experience (QoE) with lower number of rerouting times, higher average quality and smoother video quality than existing non-SDN methods under different scenarios of bandwidth fluctuations.
