Design And Implementation Of Network Business Control System

The rapid development of computer networks has greatly promoted the process of the informatization of human society. Thanks to networks, our lives become more convenient then before. Great business opportunities have been brought to the telecommunications industry. However, with the popularization of network knowledge and the rapid increase of network flux, challenges have been brought, too. More and more non-benign networks using, such as the link theft, illegal VoIP, unbridled P2P applications and privately network access, have seriously affected the normal operation of the network. This problem is especially obvious for network providers, large and medium enterprises, government and educational institutions. A feasible and efficient network business analysis and control solutions emerged.This system can capture network traffic through a variety of ways. Decision will be made according to depth analysis and identification on the information captured before. This decision will be sent to the network device to accomplish controlling of network with the help of the hardware. The user only need to view the real-time network traffic, as well as a variety of traffic messages and log on the system policy through friendly UI system, and then make some changes when necessary. The system can control the flow of the entire network automatically.This article describes the project background, status and development of content, and the core technologies and framework used in this system. Then systematically expounded Principle and realization of the project according to software engineering design process, from needs analysis, outline design, detailed design of key modules. In addition, for the design of some of the key issues, such as traffic logs received, data aggregation, strategy development, etc, this article made a more detailed analysis, and implementation details are given. Finally, the paper also gives the test cases and system testing process according to the system characteristics of the design principles.
