A scheduling service for a dynamic real-time CORBA system

Distributed real time applications have presented the need to extend the Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA) standard to support real time. The OMG has formed a real time special interest group (RT SIG) to specify requirements for extending CORBA for real time. One of these requirements involves providing global scheduling of all executions to support end to end timing constraints in the real time CORBA system. The paper describes the design and implementation of a real time scheduling service for a Dynamic Real Time CORBA system.
