Reducing the effects of cross traffic in packet-pair based bottleneck capacity measurements

The accuracy of the currently available bottleneck capacity measurement tools that use the packet pair technique is significantly affected by cross traffic and queuing delays. The impact of these factors is investigated, and a new technique is presented to overcome these effects by estimating the jitter based on packets sent around the same time as the packet pair. A tool based on this principle, Captool, measures the end-to-end bottleneck capacity by reducing these adverse effects, thereby increasing the accuracy of the end-to-end measurements.
