It is not an easy task to write a book on queuing networks when a large number of books in the topic have already been published. The authors have written a very timely book on queuing networks which can be used by people working in the area of communication networks. The basics of stochastic process have been discussed in Chapter 1 with queuing networks being introduced in Chapter 2 where the ...

Switch-based interconnects are used in a number of application domains including parallel system interconnects, local area networks, and wide area networks. However, very few switches have been designed that are suitable for more than one of these application domains. Such a switch must offer both extremely low latency and very high throughput for a variety of different message sizes. While som...

An upper bound for the convergence rate of distribution a queuing system state with infinitely many servers is obtained case where intensities incoming and service flows depend on system.

This paper presents one of the features of DS (Differentiated Services) architecture, namely the queuing or congestion management. Packets can be placed into separate buffer queues, on the basis of the DS value. Several forwarding policies can be used to favor high priority packets in different ways. The major reason for queuing is that the router must hold the packet in its memory while the ou...

Congestion is one of the major problems in today’s internet. So for managing traffic and to keep the network stable, Congestion Control algorithms are used. Queuing is one of the important method in traffic management system. This paper gives a comparative analysis of three queuing mechanisms Droptail, Random Early Detection and Non Linear Random Early Detection on the basis of various performa...

In this paper provides the results of research on the development of the method of constructing a model of customs procedures in terms of the theory of queuing systems based on their description by means of functional modeling IDEF0. The technique is based on use of the integrated IDEF0 models and theory of queuing systems with the ability to transition from a description of the system in IDEF0...

An approach, based on queuing modeling and simulation, to resource allocation for a distributed production system is examined in the paper. The problem is formulated as an objective function minimization for a queuing network. The optimization is based on the combination of analytical modeling and simulation. The analytical model is used for primary evaluation and branching for the optimization...

Due to many damages that human activities have imposed on the environment, authorities, manufacturers, and industry owners have taken into account the development of supply chain more than ever. One of the most influential and essential human activities in the supply chain are transportation which green vehicles such as electric vehicles (EVs) are expected to generate higher economic and enviro...

We present algorithms for approximating time-varying performance parameters for a Gt/G/c queuing system and for networks of such stations. The key ingredient is a formula for computing approximate sojourn time distributions for a Gt/G/c queuing system with time-varying arrivals and phase-type service times. The formula is based on transient Little laws expressing expected queue lengths and outp...
