可信高效的可用带宽测量方法研究

摘要

现有基于包对的可用带宽测量方法测量工具输出的常常不稳定,其原因是现有工具无法预测测量方差.本文通过建模和实验,提出了一种可用带宽测量方差估算公式,建立了一种可信,高效的可用带宽测量方法.%Measurement tools based on Packet-pair sampling gives results with great uncertainty in some cases. In this paper we investigate the use of a JQR bandwidth evaluation method considering a non-fluid cross traffic and present the alternative approach where the bur sty nature of the probed traffic could be taken into account. Based on the model,measurement variance and sample size can be calculated to improve the measurement accuracy.We evaluated the model in Internet environment.
