Assessing Asymmetric Fault-Tolerant Software
2010
2010 IEEE 21st International Symposium on Software Reliability Engineering
The most popular forms of fault tolerance against design faults use "asymmetric" architectures in which a "primary" part performs the computation and a "secondary" part is in charge of detecting errors and performing some kind of error processing and recovery. In contrast, the most studied forms of software fault tolerance are "symmetric" ones, e.g. Nversion programming. The latter are often controversial, the former are not. We discuss how to assess the dependability gains achieved by these
