A distributed real-time programming model is presented. It consists of a set of tasks whose segments require processor time and devices and is run on a dedicated network of microcomputers. A task is started upon receipt of an external signal or the completion of other tasks. Segments communicate via message passing and there may be a limited number of transient communication errors. A heuristic algorithm is developed to determine an upper bound upon the response time of each task. Consequently, it is useful in a hard-real-time environment to determine if response times will always be met.
