摘要

包对/串技术通过两个/多个背靠背发送的测量包所经历的散布间隔来估测一条路径的瓶颈带宽.本文分析了瓶颈带宽测量中的噪声特性

解释了在不同测量包长和测量包数情况下测量样点的分布.基于噪声分析的结论

文中提出了一种基于信号模式的滤波算法(MBFA

Model-Based Filtering Algorithm)

它利用信号模式/特征来增强信号、过滤噪声.

Abstract

The packet pair/train technique estimates the capacity bottleneck of a path from the dispersion experienced by two/multiple back-to-back packets.This paper analyzes the measured noise and explains the distributions of measured samples under different probing packet sizes and different packet train lengths.Based on the noise analysis and a 'signal model’

a new algorithm called MBFA (Model-Based Filtering Algorithm) is presented

which uses 'signal model’ to enlarge the signal and to eliminate the noise.
