Architecture and Performance Analysis of DIRSMIN: a Fault-tolerant Switch Using Dilated Reduced-stage MIN.


Book Description

Abstract: "We develop and analyze a dilated high performance fault tolerant fast packet multistage interconnection network (MIN) in this paper. In this new design, the links at the input and the output stages of a dilated banyan-based MIN are rearranged to create multiple routes for each source-destination pair in the network after removing one stage in the network. These multiple paths are link- and node-disjoint. Fault tolerance at low latency is achieved by sending multiple copies of each input packet simultaneously using different routes and different priorities. This guarantees that high throughput is maintained even in the presence of faults. Throughput is analyzed using simulation and analysis and we show that the new design has considerably higher performance in the presence of a faulty switching element (SE) or link in comparison to dilated networks. We also analyze the reliability and show that the new design has superior reliability in comparison to competing proposals."




Interconnection Network Reliability Evaluation


Book Description

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).




Performance Evaluation and High Speed Switching Fabrics and Networks


Book Description

A handy source for practicing engineers and researchers, this book offers collected examples of successful performance evaluation of high speed telecommunications switching fabrics such as ATM networks and high speed interconnection technology for computers. It emphasizes the performance evaluation of such switches as they apply to predicting a proposed system's performance through the use of statistical models -- a cost-saving way for communications engineers to test the design of a system without having to construct it.




Broadband Packet Switching Technologies


Book Description

Complete and comprehensive coverage of packet switching concepts and technologies The rapid growth of Internet traffic has spurred a new concentration on IP routers and ATM, MPLS, and optical switches. This book addresses the basics, theory, architectures, and technologies for implementing ATM switches and IP routers. It focuses on the architecture for the next generation of broadband switches and routers and provides detailed treatment of both theoretical and practical topics for professionals and students alike. Broadband Packet Switching Technologies is written with engineers and industry researchers in mind. It describes the basic concepts and fundamentals of ATM switches and IP routers, then divides the switches into different categories. In each category, the authors discuss the operations, problems, strengths, and weaknesses of the switches in performance and implementation. Detailed solutions and algorithms are also provided. The authors also extend fundamental packet-switching concepts to wireless and fiber-optic networks. Broadband Packet Switching Technologies fills the need for a textbook and reference dedicated to high-speed networking technologies that serves the specific needs of professionals in the telecommunications industry and provides expert material for students in related fields.

Performance Engineering of Computer and Telecommunications Systems


Book Description

This book is the proceedings of the Workshop on the Performance Engineering of Computer and Telecommunications Systems. The workshop Was held at Liverpool John Moores University, England on the 5th and 6th September 1995. The workshop follows a series organised by the British Computer Society (BCS) Special Interest Group on Performance Engineering. The workshop addressed most techniques and experieI1ces in the Engineering of Computer and Telecommunications Systems that provide a guaranteed quality of service. Techniques such as measurements, simulation, and analytical models and their applications to ATM networks, Multimedia Systems, Distributed Systems, Access and Wide Area Networks were presented. In addition a number of papers dealt with advances in the development of analytical models, simulation architectures and the application of formal methods, stich as Process Algebra, to the specification and building of performance biased computer systems. The book is suitable for systems designers, engineers, researchers and postgraduate students interested in the design and implementation of Computer Systems, Networks and Telecommunications. Many people assisted in the arrangements and success of this workshop. I would like to thank them all and in particular the reviewers. I would also like to particularly thank our industrial sponsors GPT Public Networks Group, Liverpool and BICC Cables, Chester, England for their generous financial and material support.
