Abstract

Many real-time systems use preemptive priorities in their internals to guarantee certain real-time performance. This includes technologies that range from RTSJ (The Real-Time Specification for Java) to middleware like Real-Time CORBA (Common Object Request Broker Architecture) which offers additional models and policies that blend client and server information. This decision makes easier the integration of real-time acceptance tests and dispatching policies in these kinds of infrastructures. In this paper, we analyze different tradeoffs that emerge from the definition of different propagation models for distributed real-time Java. The paper covers technological integration aspects, impact on interfaces, and other practical issues more related to the performance that this model offers to a real-time application
