Abstract

In this paper, we focus on the determination of end-to-end delay bounds for FIFO accumulation networks with leaky bucket constrained sources, including IP and ATM network cases. We determine an upper bound for the overall end-to-end delay and prove its accuracy to approximate the exact maximum end-to-end delay for accumulation networks of any size. This is achieved through an original trajectory analysis approach. Numerical studies further illustrate this point. This extends our previous results for the two-server and proves that this bound may be used as an accurate criterion for a CAC algorithm providing a deterministic QoS guaranteed service.
