The most important uses of computing in the future will be those related to the global "digital convergence" where all computing becomes digital and internetworked. This convergence will be propelled by new and advanced applications in storage, searching, retrieval and exchanging of information in a myriad of forms. All of these will place heavy demands on large parallel and distributed computer systems because these systems have high intrinsic failure rates. The challenge to the computer scientist is to build a system that is inexpensive, accessible and dependable. The chapters in this book provide insight into many of these issues and others that will challenge researchers and applications developers. Fault-Tolerant Parallel and Distributed Systems is a coherent and uniform collection of chapters with contributions by several of the leading experts working on fault-resilient applications. The numerous techniques and methods included will be of special interest to researchers, developers, and graduate students.

The most important uses of computing in the future will be those related to the global `digital convergence' where all computing becomes digital and internetworked. This convergence will be propelled by new and advanced applications in storage, searching, retrieval and exchanging of information in a myriad of forms. All of these will place heavy demands on large parallel and distributed computer systems because these systems have high intrinsic failure rates. The challenge to the computer scientist is to build a system that is inexpensive, accessible and dependable. The chapters in this book provide insight into many of these issues and others that will challenge researchers and applications developers. Included among these topics are: Fault-tolerance in communication protocols for distributed systems including synchronous and asynchronous group communication. Methods and approaches for achieving fault-tolerance in distributed systems such as those used in networks of workstations (NOW), dependable cluster systems, and scalable coherent interfaces (SCI)-based local area multiprocessors (LAMP). General models and features of distributed safety-critical systems built from commercial off-the-shelf components as well as service dependability in telecomputing systems. Dependable parallel systems for real-time processing of video signals. Embedding in faulty multiprocessor systems, broadcasting, system-level testing techniques, on-line detection and recovery from intermittent and permanent faults, and more. Fault-Tolerant Parallel and Distributed Systems is a coherent and uniform collection of chapters with contributions by several of the leading experts working on fault-resilient applications. The numerous techniques and methods included will be of special interest to researchers, developers, and graduate students.

"Lucas [examines the cybercrime] confronting our security--both for individuals and nations. The uncomfortable truth is that we do not take cybersecurity seriously enough. Strong regulations on automotive safety or guidelines for the airline industry are commonplace, but when it comes to the Internet, it might as well be the Wild West. Standards of securing our computers and other Internet-connected technology are diverse, but just like the rules of the road meant to protect both individual drivers and everyone else driving alongside them, weak cybersecurity on the computers and Internet systems near us put everyone at risk"--Dust jacket flap.

Today computing systems are more and more complex and they assume more and more responsibilities in all sectors of human activity. Unfortunately, many faults can harm the development or the use of these products. Destructive mechanisms transform faults into errors and finally failures altering the delivered service. For critical systems, the consequences of these failures can be catastrophic, but for most non-critical systems, failures are nowadays unacceptable. Hence, it is necessary to take dependability attributes into account, along the product lifecycle. This book aims at providing a general overview of the dependability of computing systems: impairments and protective means. Issues, concepts and techniques are considered from a system point of view, and are illustrated by both hardware and software technologies. An important pedagogical effort has been made: the explanations are illustrated by 370 figures, 80 examples, and 97 exercises with complete answers. A glossary of more than 500 entries defines the important terms.
