Abstract

To ensure the high availability, the duplex-computer system with fault tolerance architecture is used in crucial projects. The similarites and differences of the two results from the duplex system have been the key difficulty of this domain. In this paper, there are great progresses in the analysis of availability, the judgement over of two results and the switch over two systems. The techniques have been realized in an important project with significant effect.
