This paper specifies a procedure to derive traffic volume information for distribution of object-oriented applications. An accurate picture of traffic volumes between application components and sites, and among application components is crucial for effective design of any distributed application. The procedure represents a considerable improvement over the traditional practice of requiring application designers to provide best guess estimates of traffic volumes among application components. This approach exploits knowledge about the way in which objects are to be fragmented to compile the required traffic volumes. The knowledge utilized includes information on attribute values and messaging needed for transaction scenarios. Estimates of traffic volume generated by this procedure are of immense help to the application designer during the allocation phase of object-oriented system distribution. The procedure is amenable to automation, and has been successfully applied to a real-world application.
