摘要: 机载网络是航空电子系统的重要部分.从航电系统对数据传输的需求出发,研究了光纤通道(FC,Fibre Channel)网络复杂混合拓扑的建模与仿真.在协议分析的基础上,将不同拓扑结构的网络抽象成终端与交换机模型的组合,并分别建模.基于离散事件系统仿真方法构建了适合航空电子环境的FC网络仿真平台,并提供网络吞吐量、延迟和实时性等性能指标的评价方法.仿真结果与实测数据相对比,误差小于10%,验证了模型的有效性.使用仿真模型进行案例分析,对机载FC网络做出性能评价.Abstract: Airborne network is an important part of the avionics system. According to the data transmission demand of avionics system, modeling and simulation of mixed complex topology fibre channel (FC) network was studied. Terminal model and switch model which can compose networks with different topology were built, based on the analysis of FC protocol. The FC network simulation platform which fits for the environment of avionics based on the discrete events system simulation method was built, and method of evaluating performance index such as throughput, delay and real-time characteristics was provided. Errors between simulation result and real data are less then 10%, which verified the accuracy of the model. A case was analyzed by the simulation model, and a performance evaluation of the airborne FC network was given.
