Model-based end-to-end available bandwidth inference using queueing analysis

End-to-end available bandwidth estimation between Internet hosts is important to understand network congestion and enhance the performance of Quality-of-Service (QoS) demanding applications. In this paper, we investigate model-based available bandwidth measurement via the use of an active probing stream. A general end-to-end measurement framework, which unifies the current research approaches and highlights insights for measurement practice, is proposed. Within this framework, the end-to-end available bandwidth is inferred based on the measurement of the performance metrics of an active probing stream. We study two probing streams: Poisson and periodic probing. Of particular interest to our investigations is the Squared Coefficient of Variation (SCV) of the inter-probing packet arrival time at the receiver. The performance comparison of the available bandwidth measurements based on loss models and delay models indicates that the delay-based measurement exhibits many advantages over th...
