城域网骨干网络业务流量的性能分析

Performance Analysis of MAN Backbone Net Traffic

近期研究分析表明很多信息源会产生在多时间尺度下具有自相似特性的信息流,本文分析了西安宽带多媒体城域网骨干网的数据流量分布特性,以及自相似特性,实验表明真实骨干网的流量分布接近正态分布,并且具有共同特性,即左尾比正态分布短,右尾比正态分布长,即正态右偏性。

In recent years many measurements have shown that the real net traffic has self-similarity over several time scales. In this paper, we discuss the distributing properties and self-similarity of XI'AN MAN backbone network.. The experiment result has shown that normal distributing matches the backbone traffic better than others, and has found that the left-tail (right-tail) of backbone traffic is shorter (longer) than that of normal distributing , that is to say, the backbone distributing is righter than normal distributing.
