A Finite Capacity Priority Queue with Discouragement
In this paper we report on a study of a two level preemptive priority queue with balking and reneging for lower priority level. The inter-arrival and the service times for both levels follow exponential distribution. We use a finite difference equation approach for solving the balance equations of the governing queuing model whose states are described by functions of one independent variable. H...
متن کاملScalable Hardware Priority Queue Architectures for High-Speed Packet Switches
ÐWith effective packet-scheduling mechanisms, modern integrated networks can support the diverse quality-of-service requirements of emerging applications. However, arbitrating between a large number of small packets on a high-speed link requires an efficient hardware implementation of a priority queue. To highlight the challenges of building scalable priority queue architectures, this paper inc...
متن کاملThe Permutational Power of a Priority Queue
A priority queue transforms an input permutation cr of some set of size n into an output permutation z. It is shown that the number of such pairs (a, z) is (n + 1)"1 Some related enumerative and algorithmic questions are also considered.
متن کاملPriority queue classes with priority update
A limitation in the design of the interface of C++ standard priority queues is addressed. The use of priority queues in Dijkstra’s shortest path search algorithm is used as an example. Priority queues are often implemented using heaps. There is a problem, as it may be necessary to change the priority of an element while it is in the queue, but finding the element from within a heap is costly. T...
متن کاملComposite Priority Queue
This paper presents formulas for calculating waiting time for customers in a queue with combined preemptive and head-ofline (nonpreemptive) priority scheduling disciplines and describes the reasoning behind them. This work has been applied in the development of programmable terminal control units. Introduction The development of programmable terminal control units has created the need for a new...
