Object-oriented real-time systems using a hybrid distributed model of Ada 95's built-in DSA capability (distributed systems annex-E) and CORBA

This paper reports on the issues in design and development of Object Oriented Real-Time Distributed Systems using Ada 95. The paper is broken into the following parts: First, one of the general distributed real-time problems is introduced as it fits the domain within Boeing. Next, prototype solutions to the distributed capabilities are introduced including the new technologies present in Ada-95 through DSA (Distributed Systems Annex-E)[2] and extended with CORBA (Common Object Request Broker Architecture) capabilities[1]. Many issues are addressed with adoption and use of these technologies especially applicable as they relate to custom fine-tuned solutions used today to solve real-time constraints. As the various distributed solutions provide different strengths, a combination of the capabilities provides an attractive option. A hybrid distributed capability composed of DSA and CORBA has been developed and is discussed as it relates to the seamless introduction with the Ada language. Finally a set of research issues are raised.
