Design Practical System Based on Packet Tracer Technology

Abstract:

This paper combines with the actual background of the university experiment teaching of computer network, analyzes the construction situation and the existing problems of networking practical training system. Then it designs and implements the network practical training system based on embedded platform. The system mainly consists of three parts: the experiment control system, embedded experiment box and training courses. PC Terminal as the client of experimental control system is developed based on .NET/C#, which supports user login via online or offline mode, updating training courses intelligently and etc. Based on ARMS embedded microprocessor and embedded Linux operating system, it designs and implements the embedded experiment box ServerBox, which interacts with user by matrix keyboard and QT interface, analyzes network protocols based on Netfilter framework in Linux kernel, and extends ARP packet processing driver in Linux kernel to implement the visual analysis and intervention for ARP protocol. The PC Terminal has a connection with ServerBox by serial port, and communicates with each other by user-defined protocol. The system has passed the project acceptance inspection, and the first edition has been used in many colleges and universities. Its effect in improving students' knowledge and practice skills for the principle of network has been gaining recognition.
