Research And Implementation Of Service Oriented Middleware Platform

Usually,in the scale of the enterprise application, the applicationruns in the heterogeneous hardware platform, operation system and networkprotocol. If distributed systems through peer-to-peer access method fordata exchange, no doubt, will greatly increase the difficulty ofdevelopment and maintenance costs. But through the use of middlewareprovides a good way to solve the problem.Middleware is located in the above of operating system and networkprotocol, under the application software.It shields the heterogeneity ofthe hardware platform, operation system and network protocol, makesapplication software can run on the different platform friendly andprovides basic platform service for application software; At the same time,through unified management,the middleware achieves safety friendly visitbetween software application, simplifies the program design anddevelopment process, reduces the whole costs of system maintenance. Atpresent, the development direction of the middleware for service oriented,more attention to service recycling and integrate effectively.This article through to the existing middleware technology ofreasonable analysis, combining the actual project design experience, dofurther research in the following aspects: on the basis of the practicalproject needs, refines the function of the middleware platform and designsthe model framework of the platform, in order to meets the requirementslike hierarchical structure, expansibility, heterogeneous, Combined with"passive" and "active" service mode, service oriented etc.; research anddesign a kind of data exchange communication protocol which supports forvariety of data transmission mode, support real-time records and filealone or hybrid transmission, this protocal as basic foundation of thedata exchange above different systems; research and design for servicescheduling, reuse and reorganization mechanism, convenient theintegration or reuse of services; raise and design a simple load balancingbased on the research of a lot of load balance technology, it can dealwith high load high concurrent access effectively. Furthermore,introduces and analysises the process of service registration,requestion,calling,responsion and cancelling.The middleware platform is applies to "data exchange platform ofcustomer service center" successfully. After a long but stable run period,proving the reasonable and practical of the design my article.
