| 摘 要： | 针对Juniper、比威和华为路由器的路由表极限性能进行研究.3种类型的核心路由器都可以支持10万条以上的IPv6路由条目.在此基础上还研究了路由器的Memory使用和CPU使用和路由条目的变化的关系.最后,还研究了大路由表情况下,路由器数据平面的转发性能,包括：传输延迟和TCP吞吐量.通过对试验历史数据分析发现,对于3种不同类型的路由器,传输延迟和TCP吞吐量的变化和路由条目增加之间并没有明显的相关性.

| Abstract: | In this paper, we proposed an experimental framework to study both control phne and data plane performance ofrouters. Our experiments studied three types of core routers in Cemet2 and found that both memory and CPU usages wiU increase due to larger routing tables. Besides, no significant correlations were found between TCP performance and large routing tables. |
