Polling Models Under Limited Service Policies: Sharp Asymptotics

Exact asymptotics for exponential polling models under a general class of limited server scheduling policies are developed. This is done for a system with an arbitrary number of customer types. We find that the asymptotic behaviour can be classified into as many regimes as there are customer types, with the boundaries between regimes depending on the system parameters. To compute exact expressions for the tail asymptotics we employ methodology …
