ABSTRACT
A simple and general design uses message-based communication to provide software tolerance of single-point hardware failures. By delivering all interprocess messages to inactive backups for both the sender and the destination, both backups are kept in a state in which they can take over for their primaries.
An implementation for the Auragen 4000 series of M68000-based systems is described. The operating system, AurosTM, is a distributed version of UNIX*. Major goals have been transparency of fault tolerance and efficient execution in the absence of failure.

The cascade fault tolerance message system
CSC '89: Proceedings of the 17th conference on ACM Annual Computer Science ConferenceThis paper addresses the problem of constructing a highly reliable message delivery system in a distributed environment. It presents a fault tolerance algorithm that guarantees the delivery of a message to its destination despite faults in one or more ...
