A QLearning Based Business Differentiating Routing Mechanism in SDN Architecture

Abstract

With the diversified development of the current network, users' demand grows as well which brings great challenge for its load ability. In this paper, we purpose a QLearning based business differentiating routing mechanism in SDN architecture to guarantee users' routing QoS. To realize that, this paper designed four modules (discovery of link, classification of link, intensive learning and Q-value table sending) to assign different paths to data streams of different attributes. The experiment shows that this algorithm can decrease the packet loss rate to less than 5% and for some of the date streams, this rate is almost 0, simultaneously, it also helps the delay problem.
