The application-orientated measurement performance evaluation of the end-to-end available bandwidth

As an important indicator for network performance, end-to-end available bandwidth is of great significance for network congestion control, QoS, traffic engineering, and network planning etc.. However, the measurement on the available bandwidth is subjected to the influences of measuring tools and the actually tested network environment. This study concluded the main factors influencing the measurement accuracy of available bandwidth and constructed a cheap and scalable measurement platform that can effectively simulate most of network environment. Through this platform, it comprehensively evaluated the measurement performance of available bandwidth in case of different influencing factors and performance indexes.
