准确的网络带宽测量对于各种网络应用非常重要。不幸的是，准确的带宽测量是困难的。我们描述了一些当前的带宽测量技术：使用吞吐量和数据包对。我们解释了这些技术的一些问题，包括准确性差、可扩展性差、缺乏统计稳健性、适应带宽变化的敏捷性差、部署缺乏灵活性以及在各种流量类型上使用时不准确。这些问题的解决方案包括使用分组窗口来快速适应带宽变化，使用仅接收端分组对来结合精确度和易于部署，以及潜在的带宽过滤来提高精确度。这些技术至少与以前使用的过滤算法一样准确，在某些情况下，它们的准确率要高出37%以上。
Accurate network bandwidth measurement is important to a variety of network applications. Unfortunately, accurate bandwidth measurement is difficult. We describe some current bandwidth measurement techniques: using throughput, and packet pair. We explain some of the problems with these techniques, including poor accuracy, poor scalability, lack of statistical robustness, poor agility in adapting to bandwidth changes, lack of flexibility in deployment, and inaccuracy when used on a variety of traffic types. The authors solutions to these problems include the use of a packet window to adapt quickly to bandwidth changes, receiver only packet pair to combine accuracy and ease of deployment, and potential bandwidth filtering to increase the accuracy. These techniques are at least as accurate as previously used filtering algorithms, and in some situations, they are more than 37% more accurate.
