A Dynamic Scheduling Service Model for Real-Time CORBA

The architecture of scheduling service specified in real-time CORBA is introduced and its limitation is analyzed in details. Through cooperation of client scheduler and server scheduler, the admission test that whether a new client is permitted to execute on a particular processing node is accomplished. Based on the admission test, a dynamic scheduling service model is proposed, which overcomes the limitation of current real-time scheduling service and can be applied to a dynamic open real-time CORBA system. At the end, a dynamic CORBA system based the scheduling service is presented.
