Abstract:A loss queueing system GI/G/m/0 is considered. Let a(x) be a p.d.f. of interarrival intervals. Assume that this function behaves like clambdaagrxagr-1 for small x. Further let B(x) be a d.f. of service time; (1/mgr) be the mean service time. Conditions are derived for the light-traffic insensitivity of the loss probability to the form of B(x) as (lambda/ mgr rarr) 0. In particular, the condition agr = 1 is necessary. Estimates for the loss probability are obtained.
Keywords:queuing systems  loss probability  analysis of systems in light traffic  insensitivity
