Abstract: Software defined network is a novel network architecture whose data path is obtained based on the global topology.In current SDN network,load balance and QoS assurance are the crucial issues which are unresolved perfectly.To this end,according to the global network information hold by the SDN controller,we proposed a differentiated business based routing mechanism in which the function of network awareness,the traffic-based business differentiating and the K shortest path algorithm are applied.Experimental results show that this mechanism can choose an optimal path which satisfies the QoS requirements for different types of data traffics,balance the load of entire network and improve the utilization of the underlying network resources.

Key words: Software defined network,Business differentiating,K shortest paths,Network awareness
