By analyzing the correlation structure of multifractal tree
it was found that multifractal has the ability to con-vert the non-stationary long-range dependence(LRD) trace to a series of short-range dependence(SRD) sequence.Based on this property
a FIR neural network traffic predictor combined with multifractal was proposed.Because the LRD fea-ture of trace is used
the multi-step performance of proposed method is much better than traditional methods.
