摘要
通过分析西安宽带多媒体城域网主要流量源以及骨干链路流量的特征,提出了基于概率密度分布的城域网流量的总体描述,刻画了流量聚合过程的一般规律。采用统计学理论分析了城域网上典型流量聚合过程,揭示了城域网流量的概率密度分布之所以呈现为gamma分布的成因。作为城域网流量gamma分布特征的应用,对未来一段时期内城域网流量分布特征的演化进行了预测。
Overall description of MAN traffic was presented and law in traffic aggregate process was illstrated with probability density distribution method based on analysis of a good number of traffic data sets collected straightly from different sources and backbone links on Xi'an broadband multimedia network. Moreover, typical traffic aggregare processes were also studied with statistical theory and cause of probability density distribution of MAN traffic, that is to say, gamma distribution, thus be discovered. As a utility of the characteristic of gamma distribution, distribution of MAN traffic in a future time was forecast.
