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.

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.
