Transient fault tolerance in redundant systems

Abstract

Outlines some problems which result from transient faults in designing fault tolerant systems. Based on this analysis, a systematic approach to effective transient fault tolerance in redundant systems is presented. The main point of this approach is to design error handling procedures, taking into account a variety of available error detection mechanisms and the context of error appearance. Implementation of these strategies required some special hardware and software. This approach is illustrated for systems with double and triple modular redundancy.<>
