Evaluation Of The MARS Fault Tolerance Mechanisms Using Three Physical Fault Injection Techniques

Abstract

By speeding up the occurrence of errors and failures, fault injection is an invaluable approach for testing fault tolerance. Fault injection can be used to test fault tolerance with respect to both hardware and software faults, but most studies have concerned the validation of fault-tolerant systems aimed at tolerating physical faults. Fault injection can be applied either on a simulation model of the target system fault-tolerant system (e.g., see [Goswami and Iyer 1992; Rimen et al. 19931 ) or on an actual hardware-and-software implementation (e.g., see [Arlat et al. 1990; Walter 19901 ).
