使用长程相关性对分组流量建模的批评

Criticisms of modelling packet traffic using long-range dependence

Richard G. Clegg, Raul Landa, Miguel Rio

摘要:

本文批评的概念,长程相关性是一个重要的贡献者真正的互联网流量的排队行为。这一观点受到两种不同的质疑。首先,一类用于模拟互联网流量的模型具有重要的理论缺陷。结果表明,这种行为是不一致的行为,真正的交通痕迹。其次,远程相关性显着影响排队性能的流量的概念进行了调查,通过破坏这些相关性,在真正的交通痕迹(重新排序)。它示出的相关性的较长的范围是不重要的,除了在一种情况下,一个非常高的负载。

英文摘要:

This paper criticises the notion that long-range dependence is an important contributor to the queuing behaviour of real Internet traffic. The idea is questioned in two different ways. Firstly, a class of models used to simulate Internet traffic is shown to have important theoretical flaws. It is shown that this behaviour is inconsistent with the behaviour of real traffic traces. Secondly, the notion that long-range correlations significantly affects the queuing performance of traffic is investigated by destroying those correlations in real traffic traces (by reordering). It is shown that the longer ranges of correlations are not important except in one case with an extremely high load.
