The Enterprise Service Bus Based On SOA Research And Application

Service-Oriented Architecture (SOA) is a component model that inter-relates an application's different functional units, called services, through well-defined interfaces and contracts between these services. To optimize the IT infrastructure and deliver the service in time to make the SOA possible, IT forum needs an intelligent structure to reduce the complexity of the service reusability, and to integrate all technologies, protocols and applications. For this reason, the IT forum creates an abstract layer focus on the "service" to reduce the underlying complexity by integrating all applications and technologies. Such a layer for services is called Enterprise Service Bus (ESB).According to the analysis for ESB technology and products, this thesis provides an ESB model based on SOA, which contains Bus-Local service register and access model promoting the performance of ESB model. Then this thesis discusses the architecture of system model, mechanism of running, analysis similar products, and then puts emphasis on SOA and ESB technology, and implements Bus-Local service register and access.The list of finished work:①Analyzes the problems in enterprise implementing integration, and points out the resolution is combine the business request and enterprise Service Bus. It includes SOA, Web Service, ESB, ESB products, and Normalized Message Router.②Based on analysis of Normalized Message Router, designs a Bus-Local service register and access model, which combines bus global register and local container register. It establishes hierarchy and tree store, combining distributed model, and resolves the problems on register.③This thesis provides a key component design, which is Bus-Local Service register and access Normalized Message Router, and achieve it.④Design the Cooperation of Design System using ESB based on SO, and archive it according to the requirement.
