Design Fault Tolerance

Lookup NU author(s): Professor Brian RandellORCiD



The aim of this paper is to provide a personal perspective on the suQject of design fault tolerance, and in particular software fault tolerance, as it has developed at Newcastle and elsewhere, and to speculate briefly on how the subject might advance in the future. The principal topics covered are the search for an appropriate set of basic concepts and definitions, the differing styles of fault masking provided by recovery blocks and N-version programs, the growing sophistication of error recovery techniques, particularly in distributed systems, and the problems of assessing the cost/effectiveness of design fault tolerance.
