《网络协议分析》课程教学方法研究

Research on the Teaching Method of "Network Protocol Analysis"

在《网络协议分析》课程中存在许多抽象和难以理解的概念,尤其是当涉及到某些具体协议的数据单元结构和通信双方的交互过程时。为了降低教学难度,提高教学效率,介绍了两种可视化教学方法:(1)利用Wireshark数据包分析软件;(2)利用网络协议仿真教学系统。结合具体实例对两者的使用方法进行了说明和比较。通过使用可视化教学方法前后学生的成绩对比和问卷调查,表明该方法切实有效、值得推广。

There are many abstract and difficult to understand concepts in the course of network protocol analysis, especial- ly involving the structure of PDU and tile interactive process of communication parties. To reduce the difficulty of teaching and learning, improve teaching efficiency, this paper introduces two visual tools of teaching： one is wireshark--a data pack el analysis software,the other is network protocol simulation leaching system. Tile use of the two methods is described with the specific examples. By comparison of the scores of students before and after using visual teaching methods,we can see that the methods are effective and worthy of being generalized.
