Design And Implement Of Message Integration Bus Base On CORBA

With the system, the equipments and the data of information integration increase continuously, the traditional special integration interface and the pute message queue are hard to adapt the change of the complicated environment gradually and it makes the program intricate.CORBA which uses the distributed computing technology which can be used on multi-platform and adapted heterogeneous industry standard of computer language is adopted in this article by combining asynchronism of message integration with channel passage mode. A message integration bus is constructed by component technology, which unites asynchronous message transfers, distributed computing, and Plug-in programming, etc. Thus the structure of information integration becomes briefly and the interface of it becomes singly like the Ethernet. The extending and management of information integration are easy to be realized.The work of this paper makes references to traffic information integration. In order to construct an extensive applicable message integration bus, the main research is as follows:Channel service that based on content is set up, and the channel is used as ALU of organizing information.Dynamic register and querying information types in the channel realize the expandability of message integration.Component interface and management rule of component lifecycle, which are based on service frame of the component that can be plugged and managed, are defined to realize the expandability of integration service.The strategy of adaptive QoS is utilized to improve performance and quality of the message transfers. Mathematic statistical method is established which aims at time of message transfers. The strategy and correlation parameter can be improved by statistical analyses.A set of standard structure of message transfers is defined that aims at the design and realization of the main function of channel service, message register, message filteration, message routing, frame of component and integration interface. Algorithms of delay check, estimate time of response and transfers pertinence are analyzed which carries out the strategy of adaptive QoS. The relevant statistical models are also founded.
