4.6. REAL-TIME DISTRIBUTED SYSTEMS
Fault-tolerant systems are not the only kind of specialized distributed systems. The real-time systems form another category. Sometimes these two are combined to give fault-tolerant real-time systems. In this section we will examine various aspects of real-time distributed systems. For additional material, see for example, (Burns and Wellings, 1990; Klein et al., 1994; and Shin, 1991).
