摘　　要：大量研究表明实际业务流存在分形特性,这对业务流的性能产生较大影响。本文针对光突发交换(OBS)网络边缘节点的汇聚业务流,在多重分形条件下利用小波变换对业务流进行尺度刻画,发现不同的业务流都具有分形特性,并且在尺度表现上有所差别,其原因是由于业务流自身的分布特征所造成的。The studies have proposed that real network Traffic has the scale characteristic, and it has impact on the performance of traffic. This paper depicts the traffic of OBS network edge node based on the wavelet transform in the multi-fractal with scale, and it discovers that the all traffic have the fractal characteristic, moreover the disparity living on the scale, which the reason is the distribution characteristics of traffic oneself.
