针对大型电子装备内部子系统间通信链路的统一网络需求,选择光纤通道作为主干网络,构建包含FC、RapidIO、以太网等多种网络协议的融合网络系统。文中对这些网络协议进行深入分析,提出统一命名、统一地址映射和地址解析服务实现不同网络间寻址的方案,遵循并保留了原有的子网协议。利用大规模现场可编程门阵列和高性能的PowerPC完成通用化的桥接模块开发,实现了不同协议之间的实时、高效转换,有效降低了多种网络协议设备互联的成本和技术风险。系统具有良好的可扩展性,并通过全面的网络管理保证了系统运行的稳定性。同时,还详细描述了不同网络之间数据传输的流程。

According to the unified network requirements of the communication link among the various subsystems within the largescale electronic equipment, a converged network system including FC, RapidIO and Ethernet Protocol is built, and fiber channel is selected as the backbone network. The network protocols are analyzed. The solution that realizes different networks addressing is proposed and it includes uniform naming, uniform address mapping and uniform address resolution service. The original subnet protocol is maintained. Using the large-scale FPGA and high performance PowerPC, general bridge module is accomplished. The real-time and high efficient conversion among different protocols is realized. The cost and technical risk of interconnection among different network protocol equipments are lowered down. The system has good expansibility, and the stability of the system is ensured by a comprehensive network administration. The process of data transmission among different networks is also described in detail.
