Abstract:One of the main concerns in software safety critical applications is to ensure sufficient reliability if one cannot prove the absence of faults. Fault tolerance (FT) provides a plausible method for improving reliability claims in the presence of systematic failures in software. It is plausible that some software FT techniques offer increased protection than others. However, the extent of claims that can be made for different FT software architectures remains unclear. We investigate an approach to FT that integ… Show more
