Research And Application Of ESB Integration Framework Based On Dynamic Message Routing

The management information systems developed by different IT companies in different stages grow rapidly in the enterprises with the development of software technologies. These systems are based on different technologies, including DBMS, development languages, Platform technologies, etc. Further more, the hardware and network environments also have large difference. These systems bring the "information isolated island" problem. To remove the "information isolated islands" problem and integrate all kinds of information systems in enterprises is an inevitable path of increasing the competitive power of the enterprise in the information era.This thesis discusses the technologies of enterprise application integrate and legacy systems at first, then choose Service-Oriented Architecture (SOA) as the princibal framework of Enterprise Application Integrates (EAI), and introduced the Enterprise Service Bus (ESB) as the major trunk load for information transmission and services interaction in SOA systems to make up the deficiencies that traditional SOA systems highly relies to the technology of distributed component and it adopts the point-to-point bus. After that, this thesis analyzed the limitations of traditional ESB software which can only routing through static configuration documents, and proposed a content based dynamic message routing mechanism which composed the predict routing and feedback filtration. Based on the mechanism, a dynamic message routing ESB framework (DMR-ESB) is proposed. This thesis made a systematic exposition on the designs and implements of the business process layer, ESB layer and services layer in DMR-ESB.Finally, this thesis analyzed the requirements of applications integrate and the status of some mobile communication company. And an integrated information system of the company has been developed according to DMR-ESB. The system successfully integrated several applications of the company in both data and workflow, and achieved the single-sign-on function. Furthermore, it also set up an integration platform for further applications. Practices indicate that, the DMR-ESB can be used to develop those flexible and efficient integrate systems.
