Traffic-aware networking for video streaming service using SDN

In this paper we propose a traffic-aware networking technique by using software-defined networking (SDN) to precisely and promptly identify video streaming packets. We performed experiments on our SDN testbed. Compared with the existing deep packet inspection (DPI) method, the proposed SDN-enabled traffic-aware packet routing technique can reduce the latency by 75% and increase the success rate for traffic identification up to 138%.
