Distributed object-oriented real-time systems using a hybrid model of Ada 95's built-in distributed capability and emerging real-time CORBA capabilities

The paper reports on the issues in design and development of object oriented real time distributed systems using Ada 95. 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) and extended with CORBA (Common Object Request Broker Architecture) capabilities. 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.
