| 摘 要： | 回顾了在网络业务流轨迹中的长相关(LRD)、自相似和尺度不变性现象;对几种层次MMPP模型做出评价,针对其中一种有潜力的模型进行分析。通过tcpdump、Tstat和AV估计器,在所测得的业务流轨迹中,利用已提出的现代网络流量满足的三个基本定律,通过交互式的自学习方法对网络流量进行MMPP建模。给出一种更精确的模型参数的适配途径,它采用了两级匹配并显示良好的效果。

| Abstract: | Firstly, it reviews long-range dependence (LRD), self-similarity and scaling in network traffic traces. Several hierarchical MMPP models are remarked and focus at a promising model. By means of tcpdump, Tstat and AV estimator using in the measured traffic traces, the proposed three essential laws are employed, and then model network traffics as MMPP through interactive self-study approach. A more exact fitting method for model parameters is presented, which exploits two-level matches and shows its good efficiency. Some conclusions are given. |
