航电环境下双冗余交换式FC网络的建模与仿真

摘要

With the analysis of the architecture, protocols and redundant mechanisms of the fiber channel ( FC ) network, a simplified pattern was proposed which FC dual redundant switched network could be divided into link, port, terminal, switch fabric and data frames.Then we develop a FC dual redundant switched network simulation toolkit, which provides some evaluating indicators including transmission delay , throughput and etc., and compare simulation results with measured ones.The delay error and throughput error are both within reasonable limits;and the variation tendency keeps the same along with communication load variation.Thus,the results indicate the proposed models could well reflect the FC dual redundant switched network characteristics.%通过分析光纤通道( Fibre Channel,FC)网络架构、协议及其冗余机制,将双冗余交换式FC网络抽象成链路、端口、终端、交换机和数据模型,开发航空电子环境下的双冗余交换式FC网络的仿真工具,仿真工具提供网络的吞吐量、数据传输延迟等网络性能评价指标.将实例网络实测和仿真的结果进行比较得出:时延误差和吞吐量误差在合理的随机变化范围内,其随通信负载的变化趋势一致,说明所建仿真模型能够反映航空电子FC网络的工作特性.
