在控制理论中,全球网络中的分组延迟应该采用什么类型的分布?

What type of distribution for packet delay in a global network should be used in the control theory?

A. M. Sukhov, N. Kuznetsova

摘要:

在本文中,数据包延迟的实验数据和两种理论类型的分布之间的对应关系进行了研究。计算表明,指数分布比截尾正态分布更能描述网络延迟数据。通过RIPE测试盒收集微秒内的精确实验数据。除了精确测量外,还对通过实用程序{ \em ping}收集的数据进行了分析,未更改主要结果。最后,给出了一个指数分布的方程,它是描述TCP/IP网络中数据包延迟过程的最佳方式。关键参数的搜索算法与正态分布相同,结果为指数分布.

英文摘要:

In this paper correspondence between experimental data for packet delay and two theoretical types of distribution is investigated. Calculations have shown that the exponential distribution describes the data on network delay better, than truncated normal distribution. Precision experimental data to within microseconds are gathered by means of the RIPE Test Box. In addition to exact measurements the data gathered by means of the utility {\em ping} has been parsed that has not changed the main result. As a result, the equation for an exponential distribution, in the best way describing process of packet delay in a TCP/IP based network is written. The search algorithm for key parameters as for normal, and an exponential distribution is resulted.
