The Design And Realization Of Configurable Message Transfer System Oriented To Applications

As for the increased bank competitions,the computer technology,which is the mainstay of bank business,during accelerating its rapid development,also brings the great challenges to computer engineers:With so many valuable existing systems, how to connect the information islands,how to integrate later systems,and how to explore the new gold mines for the new business,new corporation management. And with the considerations in investments,technology,the application area and so on,most internal banks uses different solutions and productions provided by different software providers.So,almost every application system has its own independent framework,and between them there has close coupled relationships or even information islands.But with harder competitions,latest business and service mode appear constantly,there are strong requirements which command the bank IT systems to follow with the changes of business tightly.So there has the need to connect the information island and make them cooperate each other.Based on the analysis about current limitation and future development of bank business systems, oriented to the bank business computer environments,this article introduces SOA system integration methodology and research-develops a uniform integration platform:CMTS-Configurable Message Transfer System.At present,though now SOA is not a mysterious technology any more and there are many discussion materials,papers and books that analysis SOA quite deeply,the applications of SOA in real distributed systems,especially the actual system integration samples,are few.CMTS of this article includes the SOA-ESB infrastructure and can integrate systems perfectly even without any interface changes.CMTS supports the service request and response with service abstract,and in the mean time,CMTS provides powerful visual develop tools to support the platform register,service register,message interface definition,format switch definition,business choreography and so on.In the back end,based on the pre-defined parameters,CMTS switches message format rapidly between the source and destination,supports message routing,business imbursement and also communication,security managements among platforms.Main innovation points and contribution of this paper are the following:1) The design and realization of the ESB data format switch module:As for the unchangeable of the custom’s business systems,this article adopts new middle data format instead of the standard protocol of SOA during designing,which accordingly equipped with format switch support module between all possible formats.And CMTS also reserves the change room for the future potential customization.All these can improve the flexibility of format switch remarkably and can deal with the multi-formats data of bank business system at the present and of course the future.2) The design and realization of ESB security module:With the WSS-Web service security protocol and regulations released by superintendency of banks,and based on encryption & decryption machines,CMTS is equipped with security module in ESB.This module can support the requirements of information integrality and privacy,also include related generation,management and delivery of security keys.3) The design and realization of business choreography engine based on service levels:Succeeds the advantages of BPEL,and tailors especially for the bank business systems,this engine firstly partitions the service levels according to its sequences,and then connect service elements of all levels to complete the entire choreography.During its running,this engine support business compensation, which improves the service integrality and consistency.
