[Abstract]:With the popularity of Internet services, the bandwidth of each link in the network is increasing, and the bandwidth of international exports and domestic operators is also growing exponentially. Along with the growth of bandwidth, the business and application on the network is becoming more and more abundant. At the same time, the cost and technical threshold of network attacks are greatly reduced, and a large number of attacks and abnormal traffic appear on the network. With the increasing complexity of traffic components and the emergence of massive abnormal traffic, the network management system must introduce new technical means to deeply analyze the network traffic in order to fully understand the distribution of traffic and its changing trend. In this paper, the concept of abnormal network traffic analysis, the current situation and development trend of abnormal network traffic analysis are discussed, and several methods of abnormal network traffic detection are introduced, and the control of abnormal network traffic is introduced. The network management system based on abnormal network traffic analysis is introduced. By applying abnormal network traffic analysis to network management, network manager can optimize and adjust the network according to the actual condition of network traffic, reduce the harm caused by abnormal traffic, and ensure the safe operation of network. Secondly, the key technologies of network management system based on abnormal network traffic analysis are discussed and analyzed. According to the different data acquisition technology of abnormal network traffic, the paper classifies the abnormal network traffic detection technology, introduces the related technologies of network management, expounds the current situation and functional composition of network management. Management agreements and trends. Finally, the advantages of abnormal network traffic analysis technology in network management are analyzed. Combining abnormal network traffic analysis technology with existing network management can provide a deep understanding of network failures and performance events. Maximize the potential of network resources, improve the overall efficiency of network services, optimize the utilization of network resources. Finally, according to the general situation of the system, this paper analyzes the requirements of the system, and designs a network management system based on abnormal network traffic analysis. Through the overall design of the project, the functional structure of the system is divided, and on this basis, the software implementation framework is determined. After the detailed design, coding and testing of the software, A network management system based on abnormal network traffic analysis is implemented. The network management system can predict the trend of traffic behavior in the network, make the network administrator adjust the network planning according to the characteristics of traffic behavior, optimize the allocation of network resources, and ensure the efficient operation of the network.
