A broad analysis of single server priority queues with two independent input streams, one of them Poisson

This is the authors' abstract. We don't add key points for this paper.

A single server faces a renewal stream of low and another one of high priority customers, one of them being a Poisson stream. For the preemptive resume and head-of-the line disciplines the transient behaviour of the queue is studied. Various limiting distributions are also obtained.
