Software Fault Tolerance: An Evaluation

Lookup NU author(s): Emeritus Professor Tom Anderson



In order to assess the effectiveness of software fault tolerance techniques for enhancing the reliability of practical systems, a major experimental project has been conducted at the University of Newcastle upon Tyne. Techniques were developed for, and applied to, a realistic implementation of a real-time system (a naval command and control system). Reliability data was collected by operating this system in a simulated tactical environment for a variety of action scenarios. This paper provides an overview of the project, and presents the results of three phases of experimentation. An analysis of these results shows that the software fault tolerance approach can be successfully utilised in critical real-time systems to achieve a significant improvement in system reliability.
