In order to improve the network transportation efficiency, we propose a new routing method called mixed routing strategy by considering packet generation rate is varied with time. The mixed routing strategy consists of two parts. When the packet generation rate is small, the shortest paths are used to deliver the packets, while the packet generation rate is large, we use the local routing strategy. Numerical results shown that with proper design on the shifting instances between the two routing methods according to the traffic dynamic behavior, the mixed routing has better network performance than the shortest path routing and the local routing strategy.
