| 摘 要： | 带宽是网络规划、管理和性能优化的重要指标.主动带宽测量技术可以跨越多个自治系统实现端到端的带宽测量,因此被广泛研究,目前已提出了大量的主动带宽测量算法.比较算法性能是设计精确、高效、健壮带宽测量算法的基础.本文定义算法的性能评价指标;通过大量带宽测量实验,从原理和实验结果分析指出误差累计和背景流量影响是影响现有测量算法性能的最主要原因.在此基础上,提出和实现一个任意链路带宽测量方法,该方法可以消除逐跳测量造成的误差累计和背景流量影响.

| Abstract: | Bandwidth metrics are necessary for network plan, management and performance optimization. For its merits, for example with capacity of measurement end-to-end bandwidth across several autonomous systems, a lot of algorithms on bandwidth active measurement were proposed. To compare and analyse existing methodologies is the basic for design of more precise, effective and robust bandwidth measurement algorithms. The metrics are proposed for performance evaluation of these methodologies. The lintitatiuus are discussed from principle and experimental result with bandwidth measurement experiment. Eliminating the affection of deviation accumulation and cross tragic is research direction for improving existing bandwidth measurement methodologies. An improved bmdwidth measurement method is proposed for eliminating infections of deviation accumulation caused by hop by hop measm-ement and cross traffic. |
