Design And Implementation Of Enterprise Local Area Network Monitoring System

With the rapid development of computer network, now it is not only gone into people’s lives, and contact of each industry is becoming more and more closely. In order to facilitate the company’s office and get all kinds of information required by the company, a large number of companies have formed a LAN and connected to the Internet.

Enterprises need to monitor the employee’s use of the specific content of the network, manage employee’s behavior during office hours, and ensure the interests of the enterprise itself.According to the relevant requirements, this paper developed a small and medium-sized LAN monitoring system, which can help enterprises to carry out related technical management, and meet the needs of the enterprise to monitor the employees in LAN. Paper completed as follows:1. Described the background on the subject, analyzes some of the status of domestic existence, described the significance of this issue, And the development target of this system is put forward at last.2. The knowledge concept, programming technology and related protocol are described in this paper.3. According to the requirement of LAN monitoring, the system development is analyzed in detail, and the function modules of the system are divided in detail, and the main modules are described in detail.4. Based on the analysis of system needs, the main function modules and the main flow of the system were designed, including the control end and user end.5. The system was implemented, and the running of the system has been tested, the result of the system is well, it basically meet the needs of network management.
