Wavelet and Analysis of Network Traffic Anomalies
小波及网络异常行为分析*

Because of wavelet can process data at different scales which is similar with the real network flow presents fractal/selfsimilar nature in its scaling behavior.A wavelet based distributed ID model approach to analyses network traffic was developed in detail.The model can post attack characteristic more clearly and,by way of improve the veracity,corresponding network node signals of wavelet decomposition was compared.Attacks and the model can detect attack more precisely than the previous model does.
