摘　　要：针对天地一体化智能网络流量具有长相关,且突发性强的特点,通过对多分形小波模型构造系数分布合理化选取,构建了基于威布尔分布的混合小波网络流量模型(W_OWM,Weibull of wavelet model).模型结合独立小波模型的长相关描述能力和多重分形模型的短期突发描述能力,选取威布尔分布重构流量,解决了传统多分形小波模型构造系数的分布选取与实际流量分布特性无关的问题,该模型能够准确、有效的描述天地一体化智能网络流量的行为特征.仿真分析表明:W_OWM重构流量表现了突出的重尾特性,与实际流量的分布特性相似,W_OWM多分形谱的描述贴合于实际流量多分形谱,更能体现流量的长相关性.Aiming at the integrated intelligent network traffic of the world,it has the characteristics of long correlation and strong burstiness,By rationally selecting the distribution of construction coefficients of the multi-fractal wavelet model,a hybrid wavelet network traffic model(W_OWM)based on Weibull distribution is constructed.The model combines the long-term correlation description ability of the independent wavelet model and the short-term burst description ability of the multifractal model,The model combines the long-term correlation description ability of the independent wavelet model and the short-term burst description ability of the multifractal model,This model can accurately and effectively describe the behavioral characteristics of the integrated intelligent network traffic.Simulation analysis shows that W_OWM reconstructed traffic exhibits outstanding heavy-tail characteristics,which are similar to the distribution characteristics of actual traffic.The description of W_OWM multi-fractal spectrum fits the actual traffic multi-fractal spectrum and can better reflect the long-term correlation of traffic.
