Abstract: With the development of network application, the structure and size of modern network become more complicated. Nowadays package simulation can't be competent for the network simulation tasks with those networks which has large size and high transit speed. Though fluid simulation has higher simulation efficiency, it has less simulation precision. In this paper, the fluid simulation was used to simulate network systems' background data fluid, and the package simulation was used to simulate the specific network actions. Based on this method,a new network simulation approach was presented,which realizes the integration of fluid simulation and package simulation and leverages the strong points of both simulation approaches. Compared with other similar approaches, the approach converts packages flow into a fluid flow, by this way, it gets precise simulation results come from the interaction of front data fluids and background fluids,and has more simulation precision and efficiency.
