Design of asynchronous communication based on event service of CORBA

Abstract

In order to truly achieve asynchronous communication mechanism based on CORBA,in this paper we did further study on principle of CORBA(Common Object Request Broker Architecture)event service and the type of service,and anal-ysed the communication process of a hybrid model.Then aiming at the shortages of traditional CORBA asynchronous com-munication mechanisms,on the basis of event service,we proposed an asynchronous callback model.The key of this model was separating the cycle of requesting and responsing,so forms two separate courses.Using this model,the message of re-questing and responding was separate.Through this model,the message requests and responses was noninterference from each other,the user can query response using IIOPClient at any time after sending a request,thus achieves asynchronous transmission of information.
