Abstract

Satellite network has been used as Internet access and natural disaster warning due to its advantages of wide communication coverage, fast construction speed, and stable during geological disasters. However, due to the high cost of building a satellite network, researchers still use software satellite network simulators to simulate the propagation delay, communication rate, and packet loss rate of the satellite link. Limited by the CPU performance, software network simulators have limitations in simulation authenticity and network scalability. Firstly, it is difficult for the software network simulator to load the actual load program to simulate the influence of the satellite network on the real data interaction. Secondly, as the number of end nodes and network nodes increases, the simulation time of the software network simulator will increase significantly. In this paper, we present an FPGA-based satellite network simulator, namely, SanSim, which has two advantages. First, SanSim utilizes FPGA's good programmability and high processing performance, and can process real data traffic in real time by connecting the actual satellite load, and the simulation reality is higher. Second, SanSim adopts the Match-Simulation Action abstraction. It is easy to expand the number of network simulator nodes and network links. Finally, we implemented the SanSim prototype on the FPGA platform, and then deployed two simple satellite network topologies. The experimental results verified the feasibility and efficiency of SanSim.
