摘　　要：通信鲁棒性用来衡量网络在极端情况下数据传输的可靠性。机载网络通信要求高可靠性,尤其是极端情况下的数据传输。如何测试恶劣环境下高带宽、低延迟网络的通信鲁棒性,评估网络可靠性至关重要。光纤通道以其抗干扰能力强、高传输速度等优点,成为新一代航空电子系统优选主干网络。文中结合自研FC-AE-ASM协议处理芯片设计阶段的原型验证过程,介绍一种FC-AE-ASM网络通信鲁棒性测试方法,以及设计与实现过程。该方法对于大数据量传输和通信忙碌情况下数据传输的正确性进行充分验证,通过仿真的手段模拟了真实应用环境中出现的数据传输的时间不确定性、链路故障等现象,实现对光纤网络鲁棒性的测试,对网络可靠性的评估有一定借鉴意义。The communication robustness is used to indicate the reliability of data transmission in abominable environment. The avionic network needs high reliability, especially in bad condition. It is important to test the communication robustness and evaluate the reliability of the high-bandwidth, low-latency network. As the fiber channel has advantages of high data transmission speed, anti-jamming etc,it is a good option to avionics main network. It introduces a method to test FC-AE-ASM network＇s communication robustness based on self -design FC-AE-ASM protocol chip. It tests data transmission＇s correctness in event of large data transmission and transmission busy. The method simulates sufficiently in data transmission time indeterminacy,link error etc,in order to test fiber channel network＇s communica- tion robustness. It provides a useful reference for evaluating network＇s reliability.
