[Abstract]:Network traffic control technology is a key technology in network management, widely used in government, enterprises, schools, medical and other fields. In this paper, the problem of network performance pressure is solved by using DFI and DPI network traffic control methods for continuous and accurate network traffic control in complex enterprise network environment. The system supports common application layer detection technology and depth behavior identification technology, and effectively recognizes and real-time control the content and protocols of various network traffic. In this paper, a network traffic management and control system for enterprise networks is designed and implemented from the theoretical and technical aspects. The main works and innovations of this thesis are as follows: (1) the advantages and disadvantages of existing technologies are analyzed, and some characteristics of network traffic in LAN are analyzed. The system is designed based on the practical application requirements of enterprise LAN. This paper presents a system solution and network deployment architecture for traffic management and control based on LAN. (2) the system can accurately identify network traffic protocols and contents and effectively control and clean the target network traffic. Support for a multi-dimensional presentation reporting system. In this paper, the front-end and back-end modules of network flow control system are designed and implemented. The functional partition of each module, the logical location of the module, the order of call between modules, the interdependence between modules are described in detail. (3) the function and performance of the system are repeatedly verified in the actual scene. The experimental results show that the system design scheme meets the technical requirements and has a good effect on network flow control. At the same time, the overall workload of the system is reduced, the network traffic pressure is effectively reduced, and the maintainability and manageability of the system are improved. Finally, the comparative analysis results and trend prediction are provided for administrators to analyze the network traffic distribution. It is of great significance for the optimization of enterprise network configuration, the network guarantee of key business application, and the customization and promotion of network service.
