Research And Application On Network Traffic Flow Monitoring System

With rapid development of Internet and enlargement of range of network application, the quantity of virus which spread by network is getting more and more, its endangerment is getting greater and greater. Before the virus endangers our network seriously, we can take effective measures to prevent the spread of virus. More and more people are engaged in this research.This paper tries to gathering the traffic flow data of key equipment including influx layer and core exchange layer. This data will be saved structurally and gradationally. The system can provide graphical user interface to show the historical data and real-time data intuitively by graphics mode. On the other hand, by the statistical analysis of historical flow data, the system can model the network traffic flows, and forecast short-term network flows. After that the system can analyse the network traffic abnormity. By use of the netwok management system and network security facility, we can setup a security infrastructure to monitor flows in real time, predicts the future flows, alarm some abnormal flows, respond to the abnormity automatically and immediately.The system uses relational database management system for storage and .management of network flow data. By use of Java technology and its distributed computing environment, the system separates business layer from data layer commendably. Thus it has preferable extensibility and portability.
