Real-Time Fault Tolerant Computer Systems

Abstract

This project is designed to study a new approach to software fault tolerance called analytic redundancy. It has been widely acknowledged that software failures are the most important issue in large computer system reliability. The failure rate of software has risen to 9.4 times the failure rate of hardware, and software failures have captured substantial media attention in recent years. The problem of software reliability is especially difficult, because the major recognized approaches (recovery blocks and n- version programming) are known to have serious drawbacks, and do not protect against whole classes of errors such as specification or design errors.
