In fault-tolerant components reaIized using replication, severai alternate results are produce d, from which a single correct result must be derived. This is done by a mechanism, that we call an adjudicator Ca concept more generaI than a voter), which uses as its inputs the individuaI results produced by the replicated subcomponents comprising the redundant component. This paper gives a rigouro...
