The design of a real-time event manager component

Abstract

We review the issues with the conception of real-time event based applications and propose an event manager component design. We start from the design proposed by the Real-time Specification for Java to handle asynchronous events and we extend and generalize it to form an event manager component. This component manages the relations between the triggering of distributed events, the events handlers and the resource allocations (servers and processors). The allocation process consists of setting individual event handlers to servers and servers to processors. The component uses the description of the events relations to generate a state automaton used to release their handlers. The feasibility analysis is processed at a component level and takes into account the events relations and the association of the servers with the processors (affinity).
