Analysis of NetFlow Data Based on DataRush

With the development of computer technology and network technology, the network security problem has become one of the most careful issues in the network world. Network security depend on a number of factors, the DoS attack is a familiar one to users. The design is mainly based on the DoS attack principle,by using Pervasive 's DataRush technology in the KNIMEeclipse environment, using java language to develop the corresponding node to analysis the NetFlow data generate by Cisco router, thus determine the current network status and detection of network data flow.
