queuing network model

[′kyü·iŋ ‚net‚wərk ‚mäd·əl]
(computer science)
A model that represents a computer system by a network of devices through which customers (such as transactions, processes, or server requests) flow, and queues may form at each device due to its finite service rate.

For the proposed simulation model, we used both queuing network model with the varying parameter's network topology and mathematical equations derived in our earlier work.
discussed open queuing network models with single and multiple servers [13].
This technique is based on multi-class product form queuing network models and the mean value analysis algorithm (Basket et al.
Multi-class product form queuing network models have been widely used in performance analysis of resource sharing systems, such as computer systems and communication networks (Bolch et al.
Multi-class product form queuing network models is capable of providing fairly accurate representations for many real systems.
In the analytical model, an open queuing network model (QNM) is proposed, which consists of five interacting multiclass generalized exponential (GE)-type queuing and delay systems with multiple servers and finite capacities.
Using GE-type distributions and related queuing models can help achieve performance measurements (utilization, mean queue length, and blocking probability etc) with a complex queuing network model.
