| Computer network teaching plays a significant role in computer teaching of higher education.One out of many college teaching reform issues we have to face now is that how to further improve the teaching quality in the computer network courses.Now,computer network teaching method in many colleges and universities put the theory-oriented teaching in the first place,which makes students difficult to further understand the network communication theory and all kinds of network protocols.So,it is effective way to enrich the content of experiment and course by the impactful approach and platform of experiment.Therefore,taking network protocols analysis as a background,this paper mainly discuss the research and design about computer network remote experimental teaching platform,including the follows:1) By deeply analyzing on the TCP/IP protocol stack in Linux Operation System, I successfully designed and achieved an MAC frame capture mechanism based on ARM,at the same time,carried out a closed experimental environment based on the ARM experiment platform.Without interference from outside,the transmission experiment such as ARP,IP,TCP,UDP and ICMP protocols can be carried out and packets can be captured.2) After a deeply analysis on the experiment and course requirements of computer network teaching,a network protocols remote experimental platform based on B/S was designed,which provide users a intuitive,flexible and easy-to-use graphic operation and analysis interface.On the process of design,Web service technical and design pattern were introduced,which makes the system a better expansibility.Different from the traditional frame-captured tool,this system utilizes B/S architecture and transmits data in a closed embedded experimental environment.In any time,any places and any devices,users can analyze the transmission process of network protocols by the remote experimental platform,which has a good value since it provide a brand-new teaching experiment approach. |
