Research And Application On Virtual Web Service

SOA (service-oriented architecture) become more and more pupular in this period. Based on Web service, enterprise application systems in internet environment are multiple grewing and Web service becoming marketization gradually. It's a hot research on how to use a Web service accuratly and efficiently. Nowadays, many Web services in their respective and specific server or in a LAN(local area network) have the same function. Released them on the Internet would improve their reusability.So, We have to use virtualization as a unified service interface to achieve virtual integration in the dynamic Internet environment.To satisfy the service user, implementation of the Virtual Web services unified interface dynamic invoke real services. In the process of strategic decision, service matching criterion is particularly important. Based on keyword matching strategic UDDI has a low precision ratio in service matching. Our design of virtual Web services is based on the semantic Web services, it is double match engine support more accurate and flexible service discovery. This paper research and innovation points as follows:(1)Proposed a new concept of Virtual Web Service. With the commercialization in Web service market, traditional Web service model in the Internet environment had many problems. In order to adapt to the dynamic change and improve service efficiency. The author explains the virtualization ideas into the SOA innovatively and propose a new concept:"virtual Web services". It provides a "Virtual Web service unified interface" to solve current problems.(2) The design of virtual Web service technical framework. Virtual Web services is not a new technology, but the integration of current technology of XML, Ontology, OWL-S, WordNet etc. They together provides a feasible technology framework.(3) The design of virtual Web service mechanism. Includes the structure and function of virtual Web services and its matching algorithm.(4) The practice of application of virtual Web services in the field of electronic business. According to the design of prototype of virtual Web services, the paper demonstrate the whole process of virtual Web services throght implements eight core module in the application.
