An Implementation On Key Techniques Of Intranet Management System

The 21 century is the age of Internet, more and more enterprises and institutions have build internal networks and accessed to the Internet. While enjoying the convenience, variety of Web-based disadvantage have follow. People now pay more attention to the network management and security issues and a set of internal network management system is urgent needed.There are a lot of network management systems at present. They have basically the same function and are able to meet the needs to a certain extent. Most systems only focus on the side of management and ignore the security issues. And because of the complexity of the network structure, there has not formed a method which can get the whole information of the intranet network efficiently. That brings some inconvenience to the network management.In this paper, we research on the two key technologies in the intranet management; one is network topology which based on the exchange-layer multi-subnet and the other is file encryption based on the driver-layer.A new physical layer network discovery approach is proposed based on tree-model which manages to solve the multi-subnet problem. According to the theory of Maximum Set and a set of formula, the method transforms the multi-subnet problem to single-subnet and simplifies the difficulty of the problem.A new driver-layer file encryption method is proposed in this paper. The method is completely transparent to users. Compared to the application-layer encryption method, this method is more security and faster.In the end of the paper, we introduce the implementation of the entire network management system mainly in the system deployment and important functions.
