Click is a modularised software router architecture. It is composed of the packet processing modules which can achieve simple router functions. Click is easy to configure, and its functions can be easily expanded. DHCP server is the main way of managing IP addresses of large networks at present. In order to improve DHCP server' s configurable capability and reconstruction property, in this paper we analyse the working principles of DHCP server, and realise its basic functions on Click modularised software router using the modularisation idea.Relevant functional testing and performance analyses are also made as well.%Click是一种模块化软件路由器体系结构,由能够实现简单路由功能的包处理模块组成,易于配置,可方便地进行功能扩充.DHCP(Dynamic Host Configure Protocol)服务器是目前管理大型网络中IP地址的主要方式,为了提高DHCP服务器的易配置性、可重构性,分析了DHCP服务器的工作原理,在Click模块化软件路由器上利用模块化思想实现了DHCP服务器的基本功能,并进行了相关的功能测试、性能分析.
