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。
Fiber Channel protocols define only three basic topologies and do not detail the application of specific network topologies. In order to solve the practical application of Fiber Channel network, based on the research of the existing basic topology, a new type of switch fabric is proposed. This structure is further analyzed, and the queuing theory is introduced into the modeling process. Based on the network communication process, the end-to-end delay of the queuing service network model is studied. Based on the OPNET platform, the modeling and simulation of the serial fiber channel network with different scales are carried out. The analysis of the simulation results and the comparison with the theoretical results show that the string structure can effectively guarantee the data transmission end To the end of the delay, well meet the real-time avionics system requirements.
