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.
