高性能路由器交换结构及接口标准选择研究

摘要

This paper researched switch fabric and interface choice in high performance routers. The paper first introduced the type of switch fabric. Then through the analysis of three interfaces, the paper proposed NPSI was better in routers. Finally, the paper given the realization of NPSI-based flow control mechanism in routers.%文章针对高性能路由器的交换结构及接口标准选择进行研究,首先简要地介绍了交换结构的分类,其次讨论比较了三种交换结构接口标准的优缺点,通过从数据通路和流量控制两方面分析,提出 NPSI 是高性能交换结构接口的正确选择,最后结合课题研究给出了基于 NPSI 的流控技术实现案例.
