Research And Implementation Of Enterprise Services Bus Based SOA

Open network application and the service-oriented architecture (SOA) and so on many factor influences,The enterprise is having the immense changes using the integration. SOA has become a new software basic architecture which offers an intelligent infrastructure to reduce the complexity of service reuse and then integrates all kinds of technologies, protocols and applications. Therefore, the thesis intends to construct service-oriented middleware for enterprise applications (i.e. SOA-based Enterprise Service Bus), which can shield the bottom complexity of different applications and technologies, and thus reduce coupling in application systems and enhance the interoperation between them. Main works of the thesis are as follows:(1) On basis of comprehensive analysis of Web service standards, the thesis puts forward a"three horizontal four vertical"Web service composition framework to implement the enterprise business integration. Under guide of WSCRM (Web Service Composition Reference Model), the thesis designs SOA-based Enterprise Application Integration Environment, and explicitly states the status of SOA-based Enterprise Service Bus in enterprise application integration.(2) The thesis presents the principle framework of SOA-based Enterprise Service Bus, and researches on transport adaptation chain, service adaptation chain and core services in this framework. Some characteristics of this framework as follows: Depending on multiple SOAP schedule mechanisms to enhance the flexibility and effect of SOA-based Enterprise Service Bus; Using SOAP security mechanisms to guarantee the security and trust of SOA-based Enterprise Service Bus; relying on transaction aggregation to support the transaction of SOA-based Enterprise Service Bus.(3) For clear clarification of SOA-based Enterprise Service Bus functions in typical enterprise application integration, this thesis adopts the responsibility chain to implementation one of SOA-based Enterprise Service Buses called s-ESB, where some handlers are responsible for transport adaptation, service adaptation and secure service. By comprehensive application of s-ESB to bridge some data and business workflow in Hunan Telecom, it promotes the unified construction, unified management, and unified implementation of Hunan Telecom and adapts to flexible Tele-Service.
