Abstract

In this paper we propose an approximation for the end-to-end (queueing) delay distribution based on endpoint measurements. We develop a notion of the end-to-end capacity which is defined for a path of interest. We show that the end-to-end path can be represented by a single-node model with the end-to-end capacity in the sense that the single-node model is equivalent to the original path in terms of the queue-length and the departure. Our study is motivated by the case where the end-to-end delay distribution can be approximated by an appropriately scaled end-to-end queue-length distribution. We investigate the accuracy of our approximation and demonstrate its application to admission control providing end-to-end QoS.
