Zusammenfassung

In Systemen, die Fehlertoleranz durch Einsatz von aktiv-redundanten Einheiten realisieren, werden Votierer benötigt. Bei sich widersprechenden redundanten Ergebnissen entscheiden sie, welche der Resultate als korrekt angenommen werden. Unterscheiden sich die redundanten Einheiten in ihrer Ausfallwahrscheinlichkeit, so kann eine reine Mehrheitsentscheidung zu nicht-optimalen Ergebnissen führen. Im vorliegenden Beitrag wird ein Votierer vorgeschlagen, der das mit höchster Wahrscheinlichkeit korrekte Resultat aufgrund der Ausfallwahrscheinlichkeiten der redundanten Einheiten ermittelt.

Abstract

Systems which provide fault tolerance by use of hot redundant units need a voter to come to a decision in case of contradictory redundant results. If redundant units are not identical with regard to their reliability and/or availability a decision based only on majority may be non-optimal. In this paper a voter is proposed which finds out the most probably correct result by use of the probability of failures of redundant units.
