Abstract

We have recently proposed a duality mapping for fault-tolerant system structures. Two canonical models of distributed fault-tolerant systems have been constructed and shown to be duals of each other. One model incorporates objects and atomic actions as the entities for program construction while the second model employs communicating processes with conversations. As a consequence of the duality, techniques and mechanisms which have been developed within the domain of just one of the models can be mapped and applied to the other model. The paper illustrates this point by mapping some well-known object replication techniques developed within the context of object and actions model to the communicating process model thereby revealing some interesting process replication techniques.
