摘    要:现有的星型反射内存网络集线器仍以高速数据选择器为核心器件构建,其实质还是将相连的节点组成环形拓扑结构的反射内存网络,并不是真正意义上的星型拓扑结构。针对这一问题,本文设计并实现了一种真正意义上的星型拓扑结构的反射内存网络集线器,并能够通过百兆以太网进行配置与实时监视数据传输过程中的性能指标。该集线器采用了FPGA配合8路高速串并/并串转换芯片的架构,实现了与集线器相连节点的星型拓扑结构,具有很好的并行处理能力,提高了网络数据映射速率。最后,通过实验验证了该集线器的稳定性、实时性与可靠性。

关 键 词:反射内存网络  集线器  星型拓扑结构  数据映射

Abstract:The existing reflective memory network hub is still built with high speed multiplexer as the core component, and its essence is using connected nodes to form a ring topology reflective memory network, not a star topology in the true sense. To solve this problem, the paper designed and implemented a real sense of star topology of reflective memory network hub, and it can be configured and real-time monitored during the data transmission performance through the Ethernet. The hub used the FPGA with 8-channel high-speed Serializer/Deserializer chip architecture, achieving that the nodes connected with the hub are formed a star topology. This hub had a good parallel processing capability and improved mapping of network data rate. Finally, experiments verified the stability, timeliness and reliability of the hub.
Keywords:Reflective Memory Network  Hub  Star  topology  Data Mapping
