Research of Asynchronous Communication Messaging Model Based on Time Decoupling in Distributed Object-Oriented Middleware

To solve the problem that the current distributed object-oriented middleware messaging communication mechanism doesn´t support time decoupling and service quality control, a new asynchronous communication model TIAIM (time independent asynchronous invoke model) which can support asynchronous messaging and time decoupling is presented, we adopted message conversion layer in client to pick up, package and convert the asynchronous message, and convert original request to a routed message, and we designed a software route agent to achieve asynchronous message transmission and retransmission. TIAIM model supports asynchronous messaging, time decoupling and service quality effectively. This paper also provides algorithm of message conversion layer and software route agent.
