摘要
Click是一种模块化的软件路由器体系结构,基于该体系结构用户可以根据自己的需求搭建不同功能的路由器。针对Click软件路由器支持静态路由协议的局限性,引入模块化路由器软件协议栈XORP(eXtensible Open Router Platform),实现了动态路由协议在Click软件路由器上的扩展。通过搭建实验网络拓扑环境,验证了基于Click转发平台的两种不同的动态路由协议RIP和OSPF,并进行了相关测试和性能分析。实验结果表明,Click软件路由器的转发性能与Linux内核基本一致,但相比较而言,Click软件路由器具有灵活、可扩展、模块化等不可比拟的优势。
Click is a modular software router architecture.Based on this architecture can build different functions of routers to meet our needs.As the Click router can only support static routing protocol,introduces a modular Internet protocol routing software suite XORP.Using XORP,the Click router also can support dynamic routing protocols.In this paper first set up an experimental topology network environment,and then test two different dynamic routing protocols RIP and OSPF using the Click forwarding platform,last analyze its performance.Our performance analysis shows Click software router is comparable with good forwarding performance for Linux kernel.However,compared to other forwarding platform,the Click software router has unparalleled advantages due to its flexibility,extensibility and modular.
