Abstract

CORBA presents a model of distributed computing in which distributed objects communicate using a high-level "information bus" called an Object Request Broker (ORB). In this paper we describe a problem with the current CORBA specification that makes ORB communication non-type-safe in certain situations. We describe a solution to the problem based on the use of unique identifiers, and show how it can be implemented efficiently in both stand-alone and federated CORBA-based systems.
