Abstract�� Recent research shows network traffic exhibits drastically different statistics according to scales, including one component holding most traffic and being mostly Gaussian and the other absorbing virtually all the small scale bursts. For better understanding of this phenomenon, wavelet for multiscale analysis was introduced, a novel traffic model based on wavelet was proposed. Independent wavelet model was proved to be an ideal model for the Gaussian component, while the bursty component find a better match with the multifractal wavelet model, this novel traffic model combined the merits of independent wavelet model and multifractal wavelet model. Simulation results with the real traffic show this model is flexible and parsimonious to accommodate Gaussian as well as bursty behavior on different scales.
