Abstract

A VOLTAN node is composed of a number of conventional processors on which application level processes are replicated to achieve fault tolerance. The processors of a node execute agreement and order protocols to 'keep in step'. The design and the implementation of three processor failure masking and a two processor fail-silent nodes using transputers are described in detail.
