— Multi-server and multi-queue architectures are common mechanisms used in a large variety of applications (call centers, Web services, computer systems). One of the major motiva...
We consider optimal policies for reentrant queues in which customers may be served several times at the same station. We show that for tandem reentrant queues the lastbuffer-fir...
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...
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...
