摘　　要：研究了实时CORBA调度服务的组成,并分析了它的局限性。利用客户调度器和服务器调度的协作,实现了新增应用的接纳测试。基于这种接纳测试方法,提出了一个动态调度服务模型,克服了实时CORBA调度服务的局限性,进而扩展了实时CORBA的应用范围。利用该模型,实现了一个动态、开放的实时CORBA系统。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.
