可重构路由器具有开放的体系结构,可以灵活重构,具有良好的可扩展性.Click提供了一种可重构路由开发软件平台,其基于构件的模块化特性使其在配置路由器及性能测试方面高效、灵活.文中给出了基于Click的模块化路由器性能测试方法,并设计了路由器性能测试的收发包Click结构,应用Click构件对模块化Click IPv6路由器的吞吐量、丢包率及时延进行测试.测试的方法方便灵活,且可用于可重构路由器模块和整体性能的测试.
The reconfigurable router has an open architecture.It can be flexibly reconfigured and easily extended.Click provides a software platform for developing reconfigurable routers.Based on Click element modularity,the performance measurement and router configuration are more efficient and flexible.This paper studies performance measurement method for modular IPv6 router based on Click,and designs Click structures of the traffic generators and receivers.Using Click elements,we measure the throughput,packet loss rate and latency of Click IPv6 routers.The performance measurement method designed in this paper is flexible and convenient,and can be applied to the measurement of partial or total performance of the reconfigurable routers.
