This book is concerned with the problem of replica determinism in the context of fault-tolerant real-time systems. Systematic fault-tolerance is based on the replication of services. The problem of replica determinism thereby is to assure that replicated services show consistent behavior in the absence of failures, i.e. replica determinism is a necessary condition to allow differentiation between correct and faulty services.
