Design And Implementation Of Traffic Management Subsystem In IT NMS

With the expansion of IT network scale and the evolution of the network technologies, the network behaviors and various applications are becoming more and more complicated. To monitor the network flow, analyze network features and performance, have examination and forecast of the irregular network flow are the important components in the IT network management.At the initial part, the thesis introduces the subject research background and the overall network structuring design the author engaged in. Also the author summarizes the existing methodologies on the network flow measurement and analysis, and in accordance with the managed information system characteristics primarily selects the given measurement methodology based on netflow technologies and data package analysis technologies. The thesis in detail illustrates the different modules' design schemes on the netflow management subsystems, including network flow adoption, analysis and irregular flow monitoring. Based on the above research, the thesis puts forward the proposed solutions such as subsystem physical structure and functionality realization. At the end, the thesis concludes the subsystems operation effects, associated with analysis in application. From the view of the operation, the netflow management subsystem has fulfilled the anticipated netflow management, and realized the satisfactory effects in the netflow collection and supervision. However, there is room to improve on the irregular netflow tracking and analysis.
