【Abstract】 This paper proposes a Hurst index estimation method based on autoregressive(e.g. AR) model, and presents mathematic inference process. Simulation results based on real traffic data show that the proposed method is better than those methods such as R/S, at the same time, using this method to estimate Hurst index can reveal the self-similar of real network traffic well. Thus this method can be applied to the network traffic management and network congestion control.更多还原
