Net Flow Clustering Analysis Based onSOM Artificial Neural Network

Network performance and use pattern are important for the applications.Through net flow analysis,use pattern can be gotten,there are lots of redundant information in net flow datum.Through data mining,some potential used patterns can be distinguished.The SOM clustering algorithm is used to analyze the net flow.And most users in same local network have the normal use pattern,and there still exist some exceptional use patterns,which are called outlier.
