摘　　要：为了降低网络维护成本和统一网络架构,实现面向FC的多协议融合型网络.本文给出IP over FC网关的设计方案和实现方法,详细介绍基于FPGA的嵌入式网关其系统架构和数据处理流程.同时对千兆以太网与FC之间帧格式的转换与地址映射进行仿真分析,并结合某型号航天器具体应用场景完成前期工程验证.结果表明,嵌入式IP over FC网关能够高效实现数据帧的解析与路由,协议转换最小时延为25μs,完好地实现FC与千兆以太网的无缝衔接与协议转换.In order to reduce network maintenance costs and unify network architecture,a multi-protocol convergence network oriented to FC is realized,the design scheme and implementation method of IP over FC gateway are presented,and the system architecture and data processing flow of embedded gateway based on FPGA are introduced in detail.The simulation and analysis of the frame format conversion and address mapping between Gigabit Ethernet and FC are carried out,and the preliminary engineering verification is carried out in combination with the specific application scenario of the manned spacecraft.The results show that the embedded gateway efficiently realize the data frame analytical and routing,the minimum delay of protocol conversion is 25μs,which perfectly realize FC and Gigabit Ethernet seamless convergence and protocol conversion.
