摘要
为了使学生深入理解电子邮件传输和域名解析的工作原理,设计一套电子邮件与域名解析相结合的综合型实验。先规划网络拓扑,设计IP编址方案,配置电子邮件服务器和域名服务器参数,再在Cisco Packet Tracer仿真器中实现和验证,并观察网络数据包的传输过程和报文格式。教学实践证明,该实验能显著提高学生对电子邮件协议和域名解析协议的理解,教学效果良好。
In order to make students understand the working principle of e-mail transmission and domain name resolution deeply,a set of comprehensive experiment combining e-mail and domain name resolution is designed.First,plan the network topology,design the IP address scheme,configure the parameters of e-mail server and domain name server,then implement and verify them in the Cisco packet tracker emulator,and observe the transmission process and message format of network packets.Teaching practice shows that the experiment can significantly improve students’understanding of e-mail protocol and domain name resolution protocol,and the teaching effect is good.
