Abstract : This paper describes experiments that show how the results of simple measurements can be used to design complex distributed applications. The exeriments used IONA Orbix, an Object Request Broker (ORB) that is Common Object Request Broker Architecture (CORBA) compliant. The experiments were conducted on Sun Sparc 20s and Intel Pentium 90s using the Microsoft NT 4.0 operating system. The purpose of the experiments was to obtain information about resource expenditures needed to support distributed computing and to use that information to support development methodologies for distributed applications. The paper shows why a simple division of a replacement for the Gobal Command and Control System's Track Correlation application into a specific Client and Server has little chance of success. A worked-out example experiment, using C++, and outlines of similar experiments which should be performed prior to the development of any distributed applications are also provided.
