摘　　要：光纤通道协议只定义了三种基本拓扑结构,并未对具体网络拓扑应用做详细说明。为解决光纤通道网络的实际应用问题,在对现有基本拓扑结构进行研究的基础上,提出一种新型交换机串型光纤通道网络结构。对该结构进行深入分析,将排队论引入建模过程,结合网络通信过程,通过建立串型服务台排队网络模型对其端到端延迟进行了研究。在OPNET平台下对规模不同的串型光纤通道网络进行了建模与仿真,通过对仿真结果的分析以及与理论值对比表明,在一定规模下该串型结构能够有效保证数据传输过程中的端到端延迟,很好满足了航空电子系统的实时性要求。In Fihre Channel protocol, only three kinds of basic topology structure are defined and the specific application is not introduced in detail . In order to solve the actual application problem, a kind of new switches-serial Fibre channel network was put forward. The structure was deeply analyzed and the queuing theory was introduced into the modeling process. Combined with the network communication process and the establishment of the severs-serial queuing networks model, the end-to-end de- lay was studied. The different scales of serial Fibre channel networks were modeled and simulated based on OPNET. The sim- ulation results and theoretical values show that the structure can effectively guarantee the end to-end delay in the process of data transmission and satisfy the real-time requirement of avionics system.
