Remote Control Computer Network Experiment System Based On Internet

Because science and technology change rapidly,combining experiment equipment with Internet technology has been a very important method of experiment teaching.In the computer network,students log on network equipment remotely by Internet,and complete construction of network topology,configuration of equipment,testing of computer and so on.Not only will students complete the experiment more free,but also will the management of lab improve and do not need people any more.At the same time,because the operation of repeated plug to the equipment will be avoided,it plays important role for life extension of equipment.In the light of the question of the construction of Dong Hua University Information College Computer Network Lab,the paper used the method of remote lab to make students complete experiment remotely.The chief content of the paper below:Through research and analysis,based on the hardware resource in the lab,we plan and deploy the control network for the lab,and has designed remote lab control network subsystem,including:deployment and configuration of SSL/VPN firewall,deployment and configuration of device management controller based on redirect telnet,deployment and configuration of network camera based on video transmission mechanism.What's more,use.net technology to develop teacher deploy equipment subsystem,function including:identity authentication,deployment of students,deployment of experiment content,deployment of experiment equipment and generation of experiment environment.The same,using.net technology to develop students experiment subsystem,function including:identity authentication,intelligence network experiment,request of real-time topology and request of site feedback.Among,students experiment subsystem is the core content of the paper,the part of the content includes some innovation of the paper,for instance:solve the function of intelligence network topology by vlan technology;Solve the function of the request of site topology by research and design of real-time algorithm;Solve the function of the request of site feedback by the deployment and configuration of the network camera.In the end,the paper conclude all the work and give the prospect for next research direction.
