Query, Queue, Repeat.

T he world is black and still when you wake. Query: main processing unit … intact. You wouldn't be thinking at all if it wasn't. Query: central power supply … 12%. Which should be sufficient. Queue: diagnostic loop protocol … in progress. The only way to tell how broken you are. Query: visual feeds, peripheral … defunct. Query: visual feed, central … intact.

A preemptive repeat priority queue with resampling: Performance analysis

In this paper, we analyze a discrete-time preemptive repeat priority queue with resampling. High-priority packets have preemptive repeat priority, and interrupted low-priority packets are subjected to independent retransmission attempts. Both classes contain packets with generally distributed transmission times. We show that the use of generating functions is beneficial for analyzing the system...

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 service priority over customers which are less delay-sensitive. In this contribution, we analyze a discretetime two-class preemptive repeat identical priority queue with infinite buffer space and generally distributed serv...

Stability Conditions of a Preemptive Repeat Priority Queue with Customer Transfers

This paper is concerned with the stability of a preemptive repeat priority queueing system with multiple types of customers and customer transfers between queues. Using the mean-drift method and matrix-analytic methods, simple conditions for the queueing system to be stable or instable are found. The conditions indicate that system stability depends only on the service rate of customers of the ...
