On Model-based Available Bandwidth Measurement on the Internet

In this paper, we investigated model-based available bandwidth measurement via the use of an active probing stream. An end-to-end measurement framework, which summarizes the current research efforts and highlights insights for measurement practice, is proposed. This framework helps the design of more efficient probing methodologies and enhances understanding of network performance. Of particular interest is the performance comparison of the available bandwidth measurements based on loss models and on delay models. The queueing analysis and the extensive simulations indicate that the delay-based measurement exhibits advantages over the loss-based measurements, in terms of accuracy, overhead, robustness, and so on.
