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.该文首先针对光突发交换(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提出了新的模型.其次结合具体的仿真环境,对实际业务流进行了尺度刻画,并通过性能评价验证了新模型的有效性.“,”Recently the studies have proposed that real network Traffic has the scale characteristic, and it has impact on the performance of traffic. Firstly, this paper proposes a new model based on the wavelet transform in the multi-fractal for the traffic of OBS network edge node. Then, the paper combining the simulating environment, and depicting for the real traffic in scale, it confirms the effectiveness of new model with performance evaluation.
