然后根据上述三个数据通过FGN模型产生65536个精确的自相似流量（自相似流量），然后以该流量作为仿真的驱动，驱动OPNET进行网络的仿真，统计相关的参数；-Then the above three data generated by the FGN model 65536 precision of self-similar traffic (self-similar traffic), then the flow as the driving simulation, driving OPNET

A fractional Fourier transform (FrFT) based estimation method is introduced in this paper to analyze the long range dependence (LRD) in time series. The degree of LRD can be characterized by the Hurst parameter. The FrFTbased estimation of Hu
