可用带宽估计的仿真技术

Simulation technique for available bandwidth estimation

T. G. Sultanov, A. M. Sukhov

摘要:

本文提出了一种测量可用带宽的方法,基于测试不同大小的网络数据包(可变数据包大小方法,VPS)。在此基础上,给出了该模型的适用范围,并推导了带宽上限的计算公式。通过计算机模拟,找出了可用带宽测量误差与测量次数的关系,并利用RIPE测试盒测量系统进行了实验验证,结果表明该方法优于现有的测量技术。Pathload实用程序已被选为测量的替代技术,并确保SNMP代理的可靠结果统计已直接从路由器中撤回。

英文摘要:

The paper proposes a method for measuring available bandwidth, based on testing network packets of various sizes (Variable Packet Size method, VPS). The boundaries of applicability of the model have been found, which are based on the accuracy of measurements of packet delays, also we have derived a formula of measuring the upper limit of bandwidth. The computer simulation has been performed and relationship between the measurement error of available bandwidth and the number of measurements has been found. Experimental verification with the use of RIPE Test Box measuring system has shown that the suggested method has advantages over existing measurement techniques. Pathload utility has been chosen as an alternative technique of measurement, and to ensure reliable results statistics by SNMP agent has been withdrawn directly from the router.
