Fault-Tolerant Real-Time Systems: The Problem of Replica Determinism

Real—time computer systems are very often subject to dependability requirements because of their application areas. Fly—by—wire airplane control systems, control of power plants, industrial process control systems and others are required to continue their function despite faults. Fault—tolerance and real—time requirements thus constitute a kind of natural combination in process control applications. Systematic fault—tolerance is based on redundancy, which is used to mask failures of individ...
