摘要
针对典型航电FC交换网络的架构, 综合考虑了节点、交换机整体故障和各个端口独立故障对网络可靠性的影响差异以及多种余度数量的分析需求, 建立了节点、交换机和链路故障模型、端口-端口网络故障模型以及节点-节点网络故障模型, 提供了一种基于矩阵的直观建模思路; 给出了基于仿真的故障样本生成方法和网络可靠性计算方法, 并结合案例对航电FC交换网络的可靠性进行了定量分析, 以上模型和方法可为航电FC交换网络的可靠性设计提供理论数据支持。
Abstract
Aiming at the typical avionics Fibre Channel (FC) switched network, considering the difference between the impact of the overall failure and the independent port failure on the network reliability, and also considering the demand of analysis to different redundancies, we built failure models of the node, the interchanger, the link, the port to port network, and of the node to node network, thus to provide an intuitionistic modeling idea based on matrix.A failure sample generating method and a network reliability calculating method based on simulation were provided, and a quantitative analysis was made to the avionics FC switched network reliability by use of a number of cases.The models and methods above can provide a theoretical support for reliability design of avionics FC switched network.
