An Empirical Comparison of Diffusion Approximations and Simulation in ATM Networks


We consider an ATM switch model, in which each of N sources is a Markov modulated rate process. We look at some approximations that have been proposed for p, the probability that in steady-state conditions, the buffer content exceeds x. These approximations are compared with the simulation results for p and the cell-loss ratio.
