Designing fault tolerance capabilities into real-time distributed computer systems

Some of the fault-tolerance schemes that have been established as promising ones for use in real-time distributed computer systems (DCSs) are reviewed. Major issues that remain to be resolved in the 1990s are also discussed. By and large, the design of fault-tolerant real-time DCSs is an immature field. Many of the promising fault tolerance schemes have not been adequately evaluated. It is hoped that many more testbed-based efforts will be made in the field of fault-tolerant real-time distributed computing.<>
