基于 Packet Tracer 软件的 DNS服务器实验设计

摘要

Experimental DNS server is an important part of the experimental teaching of Computer Network course ,and the foundation to accomplish WWW ,FTP ,E-mail server .This design is based on DNS server .This paper introduces the principle of Recursive Query and Iterative Query ,and discusses the design of experimental topology and parameter data .It uses the Packet T racer to simulate ,and the experimental results are verified and analyzed .A real trial of experimental teaching is conducted ,and the students provide a good feedback .%DNS服务器实验是计算机网络课程实验教学的一个重要组成部分，是实现WWW、FT P、E-mail等服务的基础。该实验设计以DNS服务器为核心，了解递归查询和迭代查询工作原理，设计实验拓扑，给出实验参数，使用Packet T racer软件进行仿真，并对实验结果进行了验证和分析。在实验教学中学生反馈良好。
