摘要
This paper describes the architecture,fundamental principle and implementation of a distributed fault-tolerant system——DFTSNA.Its objective is to combine extreme reliability with high availability in a shipboard environment.Multi-level fault tolerance is considered and several special-purpose hardware subsystems(F-T clusters)are developed.The physical and functional distribution of the system is empha- sized to meet the stringent shipboard requirements.A number of algorithms are produced to support fault-tolerant operation.
