Tail asymptotics for processor-sharing queues. (English) Zbl 1054.60094

This paper deals with the M/G/1 queue with processor sharing. The main goal of the paper is to obtain sufficient conditions for the validity of the reduced-service rate approximation which establishes a tail equivalence between the distributions of the sojourn time and the service time of a customer. The present study extends the state of the art to a wide class of processor-sharing queues including state-dependent processor sharing. The study is extended to cover queues with finite buffer and queues with impatience.
