摘要
以IEEE802.11协议教学为例,阐述了计算机网络原理教学过程中如何使用Wireshark协议分析软件,让学生直观地理解网络协议原理。简略地介绍了IEEE802.11协议,以及无线链路层帧的基本捕获方法。在分析帧结构的基础上,展示了AP信标帧、用户认证和关联过程的相关链路层帧的组成。通过观察主机和AP热点之间的数据交换过程,帮助学生学习AP热点发现、认证和关联的基本原理。实践表明,在课堂教学中使用协议分析工具能加强学生对协议的理解,同时提高教学效果。
Taking the teaching of IEEE802.11 protocol as an example, this paper expounds how to use Wireshark protocol analysis software in the teaching of computer network principle, letting students understand the network protocol principle intuitively. The IEEE802.11 protocol and the capture method of wireless link layer frame, including AP beacon frame, user authentication and association, and the composition of related link layer frame are briefly introduced. Practice shows that the use of protocol analysis tools in classroom teaching can enhance students' understanding of the protocol and also improve the teaching effect.
