Construction of CORBA based object group platform for distributed real-time services

The distributed real-time services are developing as a new programming paradigm of the distributed object computing systems. For supporting these services, we construct a new model of a real-time object group (RTOG) platform that can manage and group distributed objects for reducing their complicated managements and interfaces, and add distributed real-time requirements to real-time objects without modifying the ORB itself To construct our RTOG platform, we designed the RTOG structure, defined the timing constraints of real-time objects, and explained the functional definitions and interconnections of the components from the following viewpoints: object managements and real-time services. As results, we showed the real-time executing procedures and verified our findings by using an EDF mechanism to see whether real-time services can be applied to our platform
