Multi-server queuing analysis can be used to estimate average wait times and queue lengths at toll and parking exit plazas given arrival rates, number of servers, and service rates. These queuing models approximate the performance of queuing systems with multiple queues. While the queuing equations are useful where there are multiple servers, they do not fully reflect the operation of a toll pl...

This article presents an analysis of the performance two protocols supported by queuing systems, i.e. MQTT and AMQP. was performed using message brokers - ActiveMQ RabbitMQ. The time sending analyzed, determined on basis receiving for both in above-mentioned systems. tests were carried out proprietary applications written Java Spring application framework.

Queuing networks are popular us models of performance of computer systems and communication networks. The Research Queueing Package, Version 2 (RESQ2), is a system ,for constructing and solving extended queuing network models. We refer to the class of RESQ2 networks as “extended” because of characteristics absent from most queuing models, RESQ2 incorporates a high-level language to concisely de...

This paper describes research in and a performance comparison of the Accelerated Strategic Computing Initiative (ASCI) queuing algorithms using a newly developed simulator. The goal of this research is to develop models of the queuing systems used at the Sandia, Los Alamos, and Livermore National Laboratories (SNL, LANL, LLNL) and to study the strengths and weaknesses of the queuing algorithms....

Queuing theory is used to model many systems in different fields in our life; it is used in simple systems and complex ones. The main idea in the application of a mathematical model is to measure the performance measures of the application in order to improve the performance of the system. This paper will present an analytical method and simulation modelin estimation the appropriate model for a...

In this paper a new structure is proposed for the massive parallel processing systems. This structure is expandable in vertical and horizontal manner and cover many of the previous computer designs. The queuing theory and Jackson queuing network is applied for constructing an analytical model for the proposed structure. This model gives a closed-form solution for the system performance metrics,...
