The Design And Implementation Of Network Management Based On Anomaly Network Flow Analysis

With the popularity of the Internet service, each link bandwidth on the network is more and more big, the Internet bandwidth between the bandwidth of the international export and domestic operators also synchronized index trend growth. Along with the growth of the bandwidth, business and application on the network also unceasingly rich.At the same time, the cost of network attack and the technical threshold dropped sharply,a large number of various attack and abnormal traffic on network. In this increasingly complex flow components, under the condition of abnormal flow mass emergence,network management system must be the introduction of new technical method for analyzing the network traffic to a comprehensive understanding of various traffic distribution and trends.This paper firstly the concept of abnormal network flow analysis, the domestic and foreign research present situation and development trend are discussed, and introduces several kinds of abnormal network flow detection method, the control of the abnormal network flow, and introduces the network management system based on abnormal network flow analysis. By abnormal network flow analysis application in network management, network managers can according to the actual condition of the network traffic, the network optimization and adjustment, reduce the abnormal flow of damage,to ensure the safe operation of the network.Second, the network management system based on abnormal network flow analysis of key technology are discussed and analyzed. Based on abnormal network flow of different data collection technology, classifying abnormal network flow detection technology; An introduction to the related technology of network management,expounds the present situation of the network management, function composition,management protocol and development trend. Finally analyzes the abnormal network flow analysis technology in the application of network management advantages,abnormal network flow analysis technology combined with the existing network management can provide for the deep understanding of the network fault and performance events, to maximize the network resource potential, promote the overall benefit of network business, optimize network resource utilization.Finally, this paper, based on the overview of system to the demand of the systemare analyzed, and according to demand design a network management system based on abnormal network flow analysis. Based on the overall design of the project, divide the function structure of system, on this basis to determine the architecture of software realization, through detailed design, coding, and testing of software, realizes the network management system based on abnormal network flow analysis. The network management system can predict the network traffic behavior tendency, so that network administrator can according to the characteristics of the flow behavior, adjust the network planning, optimize the distribution of network resources, ensure the efficient operation of the network.
