Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Multiprocessors require an interconnection network to connect processors with memory modules. The performance of the interconnection network can have a large effect upon overall system performance, and, therefore, methods are needed to model and compare alternative network architectures. This paper is concerned with evaluating the performance of multistage interconnection networks consisting of k x s switching elements. Examples of such networks include omega, binary n-cube and baseline networks. We consider clocked, packet switched networks with buffers at switch output ports. An analytical model based on approximate Mean Value Analysis is developed, then validated through simulations."

This model is validated by simulations. The analytical results obtained from the model are also compared with those in multistage interconnection networks using circuit switching and packet switching."

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Multistage interconnection networks (Banyan networks) are frequently proposed as connections in multiprocessor systems or in ATM switches. There exist several analytical models describing the performance of networks in which messages are unicasted. In this paper, an analytical model for the performance evaluation of buffered Banyan networks is presented in which messages may be multicasted. In our model, an arbitrary network size, arbitrary buffer lengths in each network stage, an arbitrary (but uniform) traffic pattern, and an arbitrary network input rate can be chosen."

This book was released on 2000 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Multistage interconnection networks (Banyan networks) are frequently proposed as connections in multiprocessor systems, in ATM switches or in Gigabit Ethernet switches. There exist several analytical models describing the performance of such networks. Using analytical models the performance can be determined much faster than by simulation. On the other hand, the development of an analytical model is very time-consuming. In this paper, we present a method for an automatic and fast generation of an analytical network model. The generated analysis copes with networks of arbitrary size, arbitrary switching element sizes, arbitrary buffer lengths in each network stage, an arbitrary (but uniform) traffic pattern including multicast traffic, and an arbitrarily chosen network load."

This book was released on 1992 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper concerns the analysis of the Split-buffered Multistage Interconnection Networks (SMINs) under the favorite input load. The favorite load is a typical nonuniform traffic pattern which includes the uniform load as its special case. A new analytical model of SMINs under the favorite load is developed. The analytical results are validated through simulations. It is shown that the SMINs generally perform better under the favorite load than the SMINs under the uniform load. The analytical model itself also shows potential for evaluating other high performance switch designs."

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this correspondence, we propose a design and analysis technique for a class of Multistage Interconnection Networks (MINs). This class of MINs have finite buffers at the input side of their switch elements and operate in a synchronous packet-switched mode. We first examine the important issue of different clock periods in the synchronous MIN analysis. Then we analyze our 'small cycle' design with a simple analytical model and compare the results with that of a somewhat standard 'big cycle' model that is currently used. The significant performance improvement of our model is shown based on various clock width, data width, and buffer length."

Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel and efficient tools, techniques and approaches for reliability evaluation, reliability analysis, and design of reliable communication networks using graph theoretic concepts. In recent years, human beings have become largely dependent on communication networks, such as computer communication networks, telecommunication networks, mobile switching networks etc., for their day-to-day activities. In today's world, humans and critical machines depend on these communication networks to work properly. Failure of these communication networks can result in situations where people may find themselves isolated, helpless and exposed to hazards. It is a fact that every component or system can fail and its failure probability increases with size and complexity. The main objective of this book is to devize approaches for reliability modeling and evaluation of such complex networks. Such evaluation helps to understand which network can give us better reliability by their design. New designs of fault-tolerant interconnection network layouts are proposed, which are capable of providing high reliability through path redundancy and fault tolerance through reduction of common elements in paths. This book covers the reliability evaluation of various network topologies considering multiple reliability performance parameters (two terminal reliability, broadcast reliability, all terminal reliability, and multiple sources to multiple destinations reliability).

This book was released on 1990 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: First, a model is derived under the assumption of unbounded buffers. This model is quite straightforward and gives extremely accurate performance predictions provided that buffers are reasonably large. Next, a model for the case where buffers are bounded in size is developed. This model is considerably more complex, but, in general, predicts the behaviour of networks with small buffers more accurately."

Available in PDF, EPUB and Kindle. Book excerpt: Computer networks can be classified into two broad categories: wired networks and wireless networks, according to the hardware and software technologies used to interconnect the individual devices. Wired interconnection networks are hardware fabrics supporting communications between individual processors in highperformance computing systems (e.g., multi-computer systems and cluster systems). On the other hand, due to the rapid development of wireless technologies, wireless networks have emerged and become an indispensable part for people's lives. The integration of different wireless technologies is an effective approach to accommodate the increasing demand of the users to communicate with each other and access the Internet. This thesis aims to investigate the performance of wired interconnection networks and integrated wireless networks under the realistic working conditions. Traffic patterns have a significant impact on network performance. A number of recent measurement studies have convincingly demonstrated that the traffic generated by many real-world applications in communication networks exhibits bursty arrival nature and the message destinations are non-uniformly distributed. Analytical models for the performance evaluation of wired interconnection networks and integrated wireless networks have been widely reported. However, most of these models are developed under the simplified assumption of non-bursty Poisson process with uniformly distributed message destinations. To fill this gap, this thesis first presents an analytical model to investigate the performance of wired interconnection networks in multi-computer systems. Secondly, the analytical models for wired interconnection networks in multi-cluster systems are developed. Finally, this thesis proposes analytical models to evaluate the end-to-end delay and throughput of integrated wireless local area networks and wireless mesh networks. These models are derived when the networks are subject to bursty traffic with non-uniformly distributed message destinations which can capture the burstiness of real-world network traffic in the both temporal domain and spatial domain. Extensive simulation experiments are conducted to validate the accuracy of the analytical models. The models are then used as practical and cost-effective tools to investigate the performance of heterogeneous wired or wireless networks under the traffic patterns exhibited by real-world applications.

This book was released on 1991 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Central to all parallel architectures is a switching network which facilitates the communication between a machine's components necessary to support their cooperation. Multi-stage interconnection networks (MINs) are classified and analytic models are described for both packet-switched and circuit-switched MINs with asynchronous transmission mode. Under strong enough assumptions, packet-switching can be modelled by standard queueing methods, hence providing a standard against which to assess approximate models. We describe one such approximate model with much weaker assumptions which is more widely applicable and can be implemented more efficiently. To model circuit-switching requires a different approach because of the presence of passive resources, namely multiple links through the MIN which must be held before a message can be transmitted and throughout its transmission. An approximate analysis based upon the recursive structure of a particular MIN topology is described which yields accurate predictions when compared with simulation."
