It radically changes organization structure of information industry, development method of information product and appliance mode of information technology with fast development and popularity of network special internet technique. Enterprise internal network intranet technique based on internet is applied widely in information system construction of modern enterprise. But its requirement becomes higher to adaptive trait of appliance system and basic information construction technique with deep development of enterprise informatization process. High complication, dynamic and uncertainty is representative characteristic of current enterprise information system. The form of applications move from close, localized-oriented and static closely-coupled mode towards open, public and dynamic loosely-coupled mode. The mode transition challenges distributed object-oriented middleware in communication mechanism. Traditional distributed object-oriented synchronous communication mechanism can't adapt integration need of application component under distributed heterogeneous network environment.This paper mainly researches on technologies for decoupling time and control flow of asynchronous communication model based on distributed object-oriented middleware. Firstly, it provides and defines asynchronous polling model that implements asynchronous polling mechanism and flow decoupling. This paper discusses the architecture and core algorithms, and also proves correctness of algorithms. Secondly, this paper presents distributed object asynchronous messaging model based on time decoupling. It provides define, architecture and communication mechanism of this model. Thirdly, this paper presents message conversion layer and software route agent in distributed object asynchronous messaging model based on time decoupling. This model places important on message package, conversion mechanism and interrelated interface define of message conversion, and software route agent mechanism and interrelated algorithms. Finally, to Distributed object-oriented asynchronous messaging model based on time decoupling and communication mechanism, we test and analyze the network property in open software Mico environment.
