This textbook provides a quick and easy understanding of multistage interconnection networks (MINs) for engineers. The book contents focus on the design, performance metrics, and evaluation of these networks which are crucial in modern computer architecture. The contents equip engineering students, apprentices and professionals with in-depth knowledge and analysis of MINS, enabling them to build complex computer architectures for efficient data communications and cost effective solutions for circuit design. The book starts with an introduction to MINS and subsequently progresses to the evaluation of a range of MINS (SEN, Gamma-Minus, FTSN, FTGN, SEGIN). Key highlights of the book include: · Easy to understand notes on design, reliability and fault tolerance · Covers a wide range of MIN types with notes on design variants · Supplementary information aiding comprehension of the main content. · A curated list of references for further exploration and deeper understanding.

Provides fundamentals of reliability engineering and illustrates practical applications in the area of parallel/distributed systems (Multistage Interconnection Networks) The first part of the book (chapters 1–5) introduces the concept of reliability engineering, elements of probability theory, probability distributions, availability, and data analysis. The second part of the book (chapters 6–11) provides an overview of parallel/distributed computing, network design considerations, classification of multistage interconnection networks, network reliability evaluation methods, and reliability analysis of multistage interconnection networks including reliability prediction of distributed systems using Monte Carlo method. Fundamentals of Reliability Engineering meets the increasing demand for knowledge tools that practicing reliability professionals can use to optimize their reliability decisions. Reliability prediction is important as it determines the usability and efficiency of the network to provide services. Reliability evaluation methods discussed in this book can be applied to analyze the reliability of any other systems. As an example, reliability analysis of distributed systems that consist of layers of switching elements connected together in a predefined topology that provide the connectivity between the set of processors and the set of memory modules, are presented.

Multistage interconnection networks (MINs) can be designed for parallel computing and switching fabrics. Multistage sorting networks can be one of the many applications using interconnection networks. In this monograph, the generalized odd-even merge design is discussed in detail. Designing switching network is another important application of the multistage networks. Generally, interconnection network can be blocking, rearrangeably nonblocking, or nonblocking, or with variable connecting capabilities, from rearrangeable for permutation to nonblocking for multicast services. Novel multistage switching fabric designs, the PINIUM and PINIUM+ switches, for packet switching and multicasting are discussed. A novel switching framework of high-performance hardware schedulers for various buffering techniques based on interconnection networks are discussed.

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).
