Abstract：Recently the studies have found that real network traffic has the fractal characteristic, and it has great impact on the performance of traffic. With the convergence traffic of OBS network edge node, the author proposed a new model based on the wavelet transform under the multi-fractal condition. Different from the common fractal model, the new model considered not only the optimal of the scale factor in wavelet transform but also real network environment (such as buffer size, utilization and so on). Experimental results prove that the performance of traffic does not just relate with correlation, but also with the network environment. Finally, scale depiction and performance evaluation of traffic verify the effectiveness of the model.
