ABSTRACT:

This talk focuses on the tail characteristics of queueing networks with subexponential service times. Our objective is to analyze the tail asymptotics of various performance measures such as cycle times (system times) and waiting times on a variety of queueing models which may arise in telecommunications. First, we consider a general class of closed feedforward fork and join queueing networks with subexponential service time distributions. Our purpose is to provide the tail asymptotics of transient and stationary cycle times and waiting times. The second system is an open tandem queue with a communication or manufacturing blocking scheme. We are interested in the tail asymptotics of transient and stationary response times and waiting times.
