Design And Development Of Network Of Network Traffic Analysis System Based On Netflow

This article will explain how to analyse the abnormalities of network with the NetFlow data produced by router while present detailed design and implementation process. With this system, the manager of network can notice more information about the security of the network in order to provide a better service.First of all, this paper will describe the network traffic analysis and network monitoring technology, and then introduce NetFlow technology of Cisco. In the third chapter we will explain how to analyse the abnormal information with NetFlow and then in subsequent two chapters we will introduce the architecture of NetFlow traffic analysis system including system tools, data acquisition, data processing and storage, etc.Finally, we will summarize the defects of this system and prospect the development of NetFlow technology.
