| 摘 要： | 提出了一种新的基于小波变换和FARIMA模型的流量预测方法,首先对原始流量进行小波分解,再进行mallat算法单支重构,接着用FARIMA模型分别对重构后的单支进行预测,最后整合流量.我们用真实网络流量进行了仿真实验,验证了提出算法的预测准确性,较之首先用FARIMA模型对小波系数进行预测再进行小波重构的方法减小了预测...

| Abstract: | A new network traffic prediction scheme is proposed based on wavelet transformation and FARIMA Model.Following the decomposition of original traffic with wavelet,each branch is reconstructed with mallat algorithm.Then prediction of reconstructed branch is conducted using FARIMA Model and finally the traffic is integrated.Simulations with real network traffic have verified the precision of proposed prediction algorithm.Compared with the method that first predicts the wavelet coefficients with FARIMA model an... |
