Abstract:
In this article,we focous on the congestion problem in the data central network(DCN), according to the recent researches of congestion control algorithm,they did not consider the delay,packet loss the flow which be transformed,and couldn't guarantee the QoS attributes.So we put on a congestion control algorithm based on QoS in the SDN architecture.In our algorithm, we choose the flow which less sensitive about delay to reroute,and choose the routeA congestion control algorithm based on QoS in SDN with standered of delay and packet loss,conbine the genernic algorithm to compute the routes,according to the simulation our aogorithm can decrease the delay,packet loss and solve the problem of congestion.
