The discrete-time preemptive repeat identical priority queue
Priority queueing systems come natural when customers with diversified delay requirements have to wait to get service. The customers that cannot tolerate but small delays get serv...

Some universal limits for nonhomogeneous birth and death processes
In this paper we consider nonhomogeneous birth and death processes (BDP) with periodic rates. Two important parameters are studied, which are helpful to describe a nonhomogeneous B...

Sojourn time distributions in the queue defined by a general QBD process
We consider a general QBD process as defining a FIFO queue and obtain the stationary distribution of the sojourn time of a customer in that queue as a matrix exponential distribut...

Exact emulation of a priority queue with a switch and delay lines
Abstract All-optical packet switched networking is hampered by the problem of realizing viable queues for optical packets. Packets can be buffered in delay lines, but delay linesdo...

Fluid models of integrated traffic and multipath routing
In this paper we consider a stochastic model describing the varying number of flows in a network. This model features flows of two types, namely file transfers (with fixed volume)...

Fluid and diffusion limits for transient sojourn times of processor sharing queues with time varying rates
Abstract We provide an approximate analysis of the transient sojourn time for a processor sharing queue with time varying arrival and service rates, where the load can vary over ti...
