Research And Implementation Of Virtual Network Design And Communication Platform

With the development of information technology and the expansion of the scale of the institutions of higher learning,cultivating professionals with the ability to practice with a high-level has become a major goal in higher education.Experimental teaching as an important means and ways is essential to develop students overall quality and practical skills.The virtual experiment with outstanding flexibility and versatility,have had more and more important on scientific research,education and training in such areas.As a result,the study of virtual experiment has become an inevitable trend of the experimental teaching in colleges and universities.In this paper,by in-depth study of virtual experiment and by analyzing and summarizing deficiencies of the existing network virtual experiment,and comparing with Client/Server and Browser/Server architecture,the thesis proposes a virtual computer network experiment system based on Client/Server architecture.This subject explains the designed object,the overall frame,the designs and realizing of main function module of virtual network design experiment that author develops. Students can build network topology on the experiment system by dragging virtual switches,routers,and other network equipment by the mouse.And through the provision of software instructions and experiment instructions,students can carry out experiments by allocating command on network equipment and test experimental data.In addition,the system has actualized the experimental model of interaction,based on TCP/IP as a virtual network protocol by non-blocking communication model in the Winsock network programming,which is a useful exploration on the integrity of computer network system.Finally,the paper tests the function of the virtual computer network experiment system.The result shows that technique of the paper to elaborate and design virtual teaching experiment system can imitate the true experiment scene and meet the requirements of the actual teaching, and it is flexible and general and it have a good interaction.In addition, the system has other advantages,such as full-function,small resources, running fast,and it will play a corresponding role in the teaching practice in the future.
