The Research On Network Experiment System Based On B/s Mode

Improving students' abilitis of analyzing and solving problems through experiments is significant in teaching. Along with the development of computer technology and network technology, Web-based laboratory has appeared. Web-based laboratory is to provide laboratory services through the network. Compared with the traditional experiment which is limited on a fixed location, it can achieve the realization of experimental resource sharing and utilization, facilitate the using of experimental resources for the user. It is conducive to the development of network teaching.Network experiment system is the integrated use of computer technology and network technology. It involves many relevant techniques which contain login interface of setting up the experimental parameters, submit the experimental commands, transmit and process a range of required data. On the basis of analysis and research in the development status of Network Lab at home and abroad, the technical foundation of constructing Network Lab has been researched and analyzed, which include user-oriented client web technology, server-side related technologies and experimental device-side control techniques. Network experiment system is built on B/S-model which brings great convenience to users, reduces the burden of use and helps to improve the system's performance of maintenance, upgrade and real-time updates.User opens a browser, types the IP of the network experimental system in the address column to open the experimental interface, selects the relevant experiment, configures the experiment parameters, and then clicks the appropriate button to send control commands, programs programmed by script embedded in web pages and network services programs will automatically send a user's commands and parameters to the server, the server parses and processes the data and sends to the experimental equipment, intelligent monitoring controller will be required to drive experiment equipment, and gather equipment's running status and results, then the relevant data transmits in the opposite path, finally, modules to display results on the page will present the data to the user in a certain form, the user can make analysis of the experimental results, that is, how the network experimental system works.
