Based On Snmp-campus Network Traffic Monitoring System Design And Realization

With the rapid development of networks and communications technology, many different resolutions are proposed. And we can implement campus network in different ways. Researches on the characteristics of the traffic on these networks are very significant to the improvement of network speed and the elimination of bottle-necks. They are the foundation of network design and refinement. And they are very important components of network management.This thesis through analyzing SNMP and discussing traditional network management model, put forward a kind of realization method that can examinate network node flux and a kind of three layer network management model that based on Web. According to this model and method, carry through the system total design and the system detailed design, pass the some tools realize network flux examination and analyze system.The system can time read flux data of network node-router, since the total flux that can obtain a certain port in muter can also obtain the dynamic IP flux form, at the same time flux data can be deposited to the homologous log document, when user need these data, taking out the related data to make the picture of PNG, and put it into HTML page to give the user a vivid image of the flux data, letting the user can more faster and understand the flux instance of a network node .In the system the period of the data collection to make certain is very important, for the sake of guaranteeing the data integrality and the data security, the system adopted a method that enactment dynamic period.
