This model manages remote invokes through event driving , and supports two asynchronous invoke model such as asynchronous call back and polling ; the model uses router as message " store - forward " mechanism , and guarantees time independent invoke of loosely coupled application ; the model extends the traditional corba addressing way , defines a kind of logic object address , which can support object migration of loosely coupled application and increase transparency of object location ; the model also defines object group address , which supports message multicast and implements " i - to - n " communication model 该模型采用事件驱动的方式管理远程调用,支持异步回调和异步轮询两种异步调用模式;模型采用路由代理作为消息的“存储-转发”机制,保障了松耦合应用的时间无关调用的需求;模型扩展了传统corba的寻址方式,定义了逻辑对象地址,能够支持松耦合应用的对象迁移,提高了对象定位的透明性;模型还定义了对象组地址,支持消息组播,实现了“一对多”的通信模式。 2
