Abstract

The OSF Distributed Computing Environment (DCE) has been established as an industry standard for open distributed computing based on the client/server model. Using the case of a distributed workflow approach, it is shown that DCE is a sound technological base, but that an extended higher-level object-oriented system support is better suited for such applications. Based on these observations, experiences with the distributed object-oriented environment DC++ on top of DCE are presented. The main goal of this system case study is to illustrate how a conventional distributed environment such as DCE can be enhanced with object interaction mechanisms and object mobility support without specific system-level modifications. Finally, future requirements and current research directions for supporting mobile communication in the context of distributed object-oriented systems are outlined.
