Packaging fault-tolerant software with Ada

The ability of the Ada programming language to support a software-engineering approach to building fault-tolerant applications systems by distributed redundant abstract data types (ADTs) is discussed. It is shown that the package, the separation of the specification from the implementation parts, the typing and exception handling mechanisms, and the nondeterministic rendezvous of the Ada language contribute to the fault-tolerance of systems constructed in this fashion.<
