Abstract
This paper intends to present the major results achieved within REQUEST, a project running under the ESPRIT program, with special regard to the field of highly reliable software required in safety-critical applications. The most promising fault-tolerant architectures involving diversity, i.e. software redundancy, will be described, identifying the classes of errors which may be responsible for system failure. In order to reduce their probability of occurrence, particular features of diverse configurations have been investigated. The impact of these drivers on software reliability has been studied by means of theoretical models and of real-world experimental data. The results presented may serve as guidelines to support the development of fault-tolerant structures as well as the assessment of ultra-high reliability.
