摘　　要：采用OPNET仿真平台,建立FC-AE-1553网络的网络控制器、网络终端和交换机的节点模型以及相应的进程模型,构建仲裁环型和交换型两种拓扑网络。针对某型号空间有效载荷系统的特点,进行网络拓扑性能仿真,测试节点数量和消息长度对网络性能的影响,分析网络吞吐量随着网络负载的变化规律。结果表明:FC-AE-1553网络具备良好的实时性能,其中,仲裁环型网络的传输性能更稳定,适合节点数量较少的场合,交换型网络的实时性能更优,适合节点数量更多的场合。With OPNET, network controller, network terminal, switch node models, and their process models were established to simulate arbitration ring and fabric topology network. According to the feature of the space payload, network topology performance simulation is carried out, test the influence of node number and message length for network performance, analyze the change role of network throughput with network load. The results showed that the real-time performance of FC-AE-1553 network was perfect, the stability of the arbitration ring topology network was better, and the real-time performance of fabric topology was more excellent.
