对采用单交换机光纤通道(FC)网络的航空电子系统进行了描述，建立了网络的排队模型。根据M/G/1模型对FC网络的队列长度、服务时间等参数进行了分析和估计。在OPNET平台下对4种周边节点数不同的FC网络进行了仿真；通过仿真分析了FC网络端到端延迟和网络节点数关系，并对评估的数学模型进行了修正；研究了网络中的延迟“抖动”情况，并分析了4种FC网络各自达到延迟稳定值的时间。

The avionic system using Fiber Channel(FC) network with single switch was described and a queuing model was built up for the network.According to M/G/1 model of Queue Theory,parameters of queue length,service time and so on of this avionic system were analyzed and estimated. Four kinds of fiber channel networks with different node numbers were simulated with OPNET.With the simulation results,the relationship of end-to-end delay with node number in fiber channel network was analyzed,and the mathematic model was amended.The “jitter” of end-to-end delay was also studied,and the time needed for each kind of FC network to become stable was analyzed.
