基于小波变换的光突发交换网络业务流的研究

最近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。针对光突发交换（OBS）网络边缘节点的汇聚业务流，首先在多重分形条件下利用小波变换对业务流进行尺度刻画。同时采用分块操作、块间变化的方法对业务流进行分析，通过深入研究发现均值和方差对业务流的性能影响较大

The Research On the Traffic of OBS Network Based On Wavelet Transform

Recently the studies have proposed that real network traffic has the scale characteristic, and it has impact on the performance of traffic. With the convergence traffic of OBS network edge node, it depicts the traffic in the multi-fractal by scale based on the wavelet transform. Then, the paper using wavelet transform to analyze the dependence of the actual traffic, it divides the traffic into blocks and then internally or externally shuffles them. The test results show that mean and variance of the traffic both have great impact on performance.
