Abstract :
A VOLTAN node is composed of a number of conventional processors on which application-level processes are replicated to achieve fault-tolerance. The architecture of a family of such nodes with differing functionalities is presented. These include failure-masking, fail-signal, and fail-silent nodes. The software architectures of a three-processor failure-masking and a two-processor fail-silent node are discussed in detail. The suitability of VOLTAN nodes as building blocks of reliable distributed systems is also discussed
