Measurements and simulations of cell delays in ATM switches

, Within the RACE project EXPLOIT, traffic experiments are being performed on an ATM testbed, the EXPLOIT Testbed, which is situated in Basel. A subset of these experiments is described in this paper. Specifically, the network performance parameter cell delay, and especially the part due to queueing effects, is focused on. The aim of this paper is to compare the measurement results with the results of a generic simulation model based on renewal theory. It is shown that the simulation model predicts the delay histogram very well, but slightly underestimates the covariance over time of the delays.
