基于PCIE总线多主互连系统的设计与实现

摘要

For high-performance computing network with large bandwidth,low latency characteristics,a multi-host interconnection network switching system based on PCIe bus was presented.Differing from the traditional high-speed interconnection network,a method for separation of host and network IO was used,multiple conversions of data signals were avoided,network latency was reduced,and the utilization of network bandwidth was increased,ensuring the high availability of the network.Test results show that the system has larger bandwidth and lower latency.%针对高性能计算网络的高带宽、低延迟的特点,提出一种基于PCIe总线的多主互连的网络交换系统.区别于传统的高速互连网络,采用一种主机与网络IO分离的方法,避免数据信号的多次转换,降低网络延迟,增加网络带宽的利用率,确保网络的高可用性.仪器测试结果表明,该系统具有较高的带宽利用率和较低的数据延迟.
