Software Fault Tolerance

Fault tolerance techniques are an accepted practice in many engineering disciplines. For software construction, the concept is particularly relevant and can mean the difference between total and irretrievable loss of data, funds or ultimately life (in safety-critical applications), as opposed to the worst case of a partial or temporary systems failure. This volume covers contemporary practices and techniques, such as error detection, exception handling, monitoring mechanisms, error recovery, and fault tolerant software (such as recovery-block N-version programming, and N self-checking programming). Part 1 surveys techniques and models in software fault tolerance, while Part 2 describes applications and experiments. Practical applications include various aviation and aerospace control systems, nuclear reactors, telecommunications products and network systems.
