The Common Object Request Broker Architecture is a successful, standardized system integration framework based on distributed object technologies. An ongoing effort concerns extensions to CORBA to incorporate realtime computing needs.Although the use of objects in real-time computing is straightforward, the technical challenge lies in the replacement of static real-time computing infrastructures with a flexible real-time computing infrastructure, in which distributed real-time client and server objects canbe created and connected as needed during runtime.We propose the concept of Composite Objects'' for the integration of real-time and non-real-time computing into a single object-based framework. Within the paper, we present a methodology for creating objects which interface to CORBA without violating real-time assumptions. We present a example scenario which integrates a real-time computing architecture and CORBA components via Composite Objects''. Finally, we discuss implementation-related issues based on our experiences with ''Composite Objects''.
