Loss rate asymptotics in a GI/G/1 queue with finite buffer
(2005) In Stochastic Models20010101+01:00 21(4). p.913931 Abstract
 We consider the stationary loss rate l(K) of a GI/G/1 queue with finite buffer of size K. Let Xn = Un  Tn, n >= 1 where Un is the service time, Tn is the interarrival time and let rho be the traffic intensity. We derive sharp asymptotics for the loss rate as K > infinity, in the cases (i): rho > 1, and (ii): rho < 1 and Xn nonlattice with light tails. We also look at another reflection, related to Moran's dam model. As an example, we look at the PH/PH/1 case, where we show how to compute the asymptotic loss rate as well as the exact one and illustrate our results numerically.
