基于Packet Tracer的域名解析系统教学实验设计

Design of DNS Simulation Teaching Based on Packet Tracer

域名解析系统(DNS)是互联网上最实用的功能之一。使用Packet Tracer软件构建一个贴近真实环境的分层域名解析系统,配置简单,效果直接。实验时,只有每一位学生参与其中,通力协作,才能达成实验效果。通过实验,学生对域名解析系统有一个直观的了解,体验到网络技术带来的乐趣。

DNS is one of the most popular applications of the Internet. It is very simple to simulate a DNS when using cisco Packet Tracer and the simulation results are quite obvious. In order to get the right results out of this simulation, every student has to work hard and cooperate with each other. When the simulation completed, every student grips a solid understanding about the principles of the DNS and have a lot of fun with it.
