Title      The design and implementation of LAN monitoring system                                             

Abstract

LAN computer monitoring and control system of this implementation helps school or corporate LAN to monitor remotely and manage computers, the purpose is to improve the reliability , safety and effectiveness of local area network (LAN),it also improves the  efficiency of students or employees.

In the first,this paper study the status of LAN monitoring system, and has carried on the demand analysis. Then, it summarizes the key technology of the application of this system: the compression technology of image and the programming technology of socket network , based on these, it proposes the overall design and function of LAN monitoring system .

In the client/server mode, the entire system uses Visual c + + as development tools of the system. It realizes the acquisition, transmission, and screen display of information.It can find out all hosts in the network, and completed the the function of monitoring terminal control.

Keywords: socket program ; remote monitoring ; client/server mode; image technology
