【摘要】 文章对光突发交换(OBS)网络中的IP流量特性以及汇聚机制进行了深入的研究,通过引入ON/OFF源模型来模拟OBS网络中数据业务的自相似特性,通过对仿真进行分析,验证了ON/OFF理论模型的正确性,最后,利用合成的可控Hurst参数流量源,对几种典型的OBS汇聚算法进行了仿真分析,结果表明,这些汇聚算法对严格自相似性流量的长相关性并没有抑制效果,只是在短时间内对流量具有平滑作用.更多还原

【Abstract】 In this paper,we focus on the study of the characterization of IP(Internet Protocol) traffic and burst assembly mechanism in OBS networks,introduce a ON/OFF sources model to describe the self-similar data traffic in OBS networks. Through simulation,we proved the correctness of the ON/OFF source model. Finally,we analysed several assembly algorithms,and the result shows that these algrorithms do not change the traffic’s self-similar,it only change the traffic’s short-term properties.更多还原
