In this paper, we present a number of issues that arise in the design and building of distributed systems for time-constrained environments. These issues include: a guarantee mechanism for time-critical tasks, the possibilities of task execution in the order defined by the precedence graph, non-blocking of resources, and interprocess communication. The building of hard real-time distributed systems is related to the implementation of these systems in the local area networks. Each implementation of the distributed hard real-time system regards the problem of what must be controlled by the operating system or bt the real-time application. In this paper, we also present othes issues associated with the implementation of these, namely: task scheduling, resource management, real time synchronization. We examine some examples of the existing distributed systems, describe their structuring and implementation, and compare their principal features.
