Because of our present inability to produce error-free software, software fault tolerance is and will continue to be an important consideration in software systems. The root cause of software design errors is the complexity of the systems. Compounding the problems in building correct software is the difficulty in assessing the correctness of software for highly complex systems. After a brief overview of the software development processes, we note how hard-to-detect design faults are likely to be introduced during development and how software faults tend to be state-dependent and activated by particular input sequences. Although component reliability is an important quality measure for system level analysis, software reliability is hard to characterize and the use of post-verification reliability estimates remains a controversial issue. For some applications software safety is more important than reliability, and fault tolerance techniques used in those applications are aimed at preventing catastrophes. Single version software fault tolerance techniques discussed include system structuring and closure, atomic actions, inline fault detection, exception handling, and others. Multiversion techniques are based on the assumption that software built differently should fail differently and thus, if one of the redundant versions fails, it is expected that at least one of the other versions will provide an acceptable output. Recovery blocks, N-version programming, and other multiversion techniques are reviewed.Torres-Pomales, WilfredoLangley Research CenterSOFTWARE ENGINEERING; SOFTWARE RELIABILITY; COMPUTER PROGRAMMING; COMPUTER PROGRAMS; FAULT TOLERANCE; APPLICATIONS PROGRAMS (COMPUTERS); SOFTWARE DEVELOPMENT TOOLS; OPERATING SYSTEMS (COMPUTERS); COMPUTER SYSTEMS DESIGN; COMPLEX SYSTEMS; COMPONENT RELIABILITY; QUALITY CONTROL

The production of a new version of any book is a daunting task, as many authors will recognise. In the field of computer science, the task is made even more daunting by the speed with which the subject and its supporting technology move forward. Since the publication of the first edition of this book in 1981 much research has been conducted, and many papers have been written, on the subject of fault tolerance. Our aim then was to present for the first time the principles of fault tolerance together with current practice to illustrate those principles. We believe that the principles have (so far) stood the test of time and are as appropriate today as they were in 1981. Much work on the practical applications of fault tolerance has been undertaken, and techniques have been developed for ever more complex situations, such as those required for distributed systems. Nevertheless, the basic principles remain the same.

Software-Implemented Hardware Fault Tolerance addresses the innovative topic of software-implemented hardware fault tolerance (SIHFT), i.e., how to deal with faults affecting the hardware by only (or mainly) acting on the software. The first SIHFT techniques were proposed and adopted several decades ago, but they have been the object of new interest in the past few years, mainly due to the need for developing low-cost safety-critical computer-based applications in fields such as automotive, biomedics, and telecommunications. Therefore, several new approaches to detect, and when possible correct, transient and permanent faults in the hardware have been recently proposed. These approaches are innovative (with respect to those proposed in the past) since they are of higher applicability (often starting from the source-level code of an application) and generality, being capable of coping with many different fault types. The book presents the theory behind software-implemented hardware fault tolerance, as well as the practical aspects related to put it at work on real examples. By evaluating accurately the advantages and disadvantages of the already available approaches, the book provides a guide to developers willing to adopt software-implemented hardware fault tolerance in their applications. Moreover, the book identifies open issues for researchers willing to improve the already available techniques.

The first ESPRIT programme contained several ambitious projects. of which REQUEST. with its wide brief covering all issues of assessment of quality and reliability of software process and product. was one. Within REQUEST. the research described in this volume. concerning those special problems of software that is required to have extremely high reliability. was particularly difficult and ambitious. The problems of software reliability are essentially twofold. On the one hand there is a concern with methods for achieving adequate reliability. on the other hand there is a need to evaluate what has actually been achieved in a particular case. Naturally. far more effort has been spent over the years on the former problem; indeed. there is a sense in which all of conventional software engineering can be seen as a response to this problem. However. it is becoming clearer than ever that we can only claim to have a truly sCientific approach. and so justify the description software engineering. when we are able to measure the attributes of process and product. It is still common to find software development methods recommended to users on purely anecdotal grounds. This is not good enough. Rational choices between rival approaches can only be made on the basis of quantified costs and benefits. Even more worrying is the tendency to argue that a software product can be depended upon merely because it has been developed by honest men using such anecdotal 'good practice'.
