On end-to-end bandwidth analysis and measurement

Many applications are interested in the end-to-end bandwidth of a path. Several tools have been implemented focusing on path capacity, but available bandwidth estimation is still an open problem to be investigated. We propose an end-to-end bandwidth measurement methodology with active probe based on packet pair technology. Our method can measure the path capacity in condition that the competing traffic is light and available bandwidth is get if the competing traffic is heavy. We also present a novel algorithm for filtering the measurement data.
