Abstract

The problem of constructing reliable processors, hereafter referred to as nodes, out of conventional unreliable processors is examined. We assume that a node is composed of a number of processors and failed processors can exhibit arbitrary behavious. The non-faulty processors o a node execute Byzntine agreement protocols to maintain the abstraction of a fail-controlled (well-behaved) node. the paper presents a variety of node architectures for maintaining the abstraction of fail controlled behaviour with differing functionalities. Some of these architectures are shown to be of practical interest.
