摘要
将局域网接入互联网的方式有多种,掌握这些接入方式是计算机网络专业学生的基本技能,学生既要掌握理论知识,又要通过实验真正实现这些接入方式。路由器自动拨号上网是常见的接入互联网的方式,该方式主要涉及PPPoE、PAT技术。由于实验条件限制加上传统仿真软件不能仿真该实验的不足,传统教学方式中仅仅是理论知识的讲解,不能达到很好的教学效果。新的EVE-NG仿真软件避免了传统仿真软件不足能够仿真该实验。学生通过该仿真软件能够独立完成从网络结构搭建到设备配置,直至系统测试全过程。实验过程加强了学生对路由器拨号上网进一步理解,同时为高校教师仿真类似实验提供借鉴。
There are many ways to connect the LAN to the Internet.Mastering these access methods is the basic skill of computer network majors.Students should not only grasp the theoretical knowledge,but also realize these access methods through experiments.Router automatic dialing up the Internet is a common way to access the Internet,which mainly involves PPPoE technology and PAT technology.Because the poor experimental conditions and the traditional simulation software cannot simulate the experiment,the traditional teaching method only explains the theoretical knowledge,and the final teaching effect is not understood.The new EVE-NG simulation software can avoid the shortage of traditional simulation software to simulate the experiment.Through the simulation software,students can complete the experiment independently,including the whole process of topology building,device configuration,and final system testing.The experiment process creates the condition for the student to understand the router dial-up process.At the same time,it can be used as a reference for university teachers to simulate similar experiments.
