随着互联网技术的快速发展,IP地址二义性所带来的弊端越来越明显,严重影响了互联网的可扩展性、移动性及安全性.Click是一种灵活的开发模块化路由器的软件平台,其提供了大量的包处理模块,可根据需要实现多种应用.本文在新网络理论体系的基础上,利用Click路由软件在接入交换路由器上实现了3种网络中身份与位置分离映射的功能,并分析了分离映射模块对接入交换路由器转发时延的影响.实验结果验证了该方法的正确性及可行性,从而为地址分离映射的具体实现提供了一种新的方法.%With the rapid development of Internet technology, today's Internet is facing serious problems in scalability, mobility and safety, which is mainly caused by the overloading of IP address semantics. Click is a new software platform for building the configurable and modular router, its building blocks are packet processing modules called elements. The ability to combine elements into a new arrangement makes our system more flexible and configurable and is very easy to implement the new applications. Based on the Architecture of New Network theory, this paper presents a new method on how to implement separation and mapping of identifier and locator in the access switch router for three kinds of network by using Click. The forwarding delay caused by the separation and mapping module is evaluated, and the result shows the correctness and feasibility in our new scheme.
