Researchs On Web Service Collabration Frame And Interrelated Technology

The web service combination includes the service composition and the service collaboration. The service composition realizes combination with the help of a center-control component and within the rules established in the stage of design. The Service collaboration realizes combination by transmitting equity messages, and choosing or invoking collaboration services at runtime. To be the main technology of dealing the more and more complexity business, the service collaboration in all probability occur some problems like collaboration service invalid, collaboration fail among service regions, suitable collaboration service is not located or collaboration can not be processed. This text researches and investigates these problems.Firstly, after analyzing two obtained web service collaboration frame, this text proposes the ECCSCF. Around the ECCSCF, every host service has an equity collaboration component helping to realize the business collaboration, which lowers the pressure of center collaboration component when it is used and reduces the coupling of the service region. The equity collaboration component of a son service region uses a service adaptation to realize the business collaboration crossed regions.Then, the text researches the web service collaboration actual effect based on the ECCSCF. It proposes the SCSLA algorithm for host services to locate collaboration services, which uses the equity collaboration component to uphold a status table, and monitors the UDDI after the status table is initialized. The status table is renewed after collaboration is happened. The status table is wagered to record the best collaboration services for the host service, and an experiment is done to test and verify the probability of SCSLA. It proposes the SCRQA algorithm for collaboration services, which premeditates the collaboration desire of the host service, the collaboration service and the affection of a third service and the quantifier of the sequence of requests arrived. The SCRQA uses the equity collaboration component to calculate the priority and queue the collaboration requests, an experiment is done to test and verify the consistency of SCSLA.Finally, the text analyzes the application of the ECCSCF and interrelated technology in e-Gov. It proposes the ECCSCF-eGov, and it also realizes the key design and deployment of equity collaboration component. The approval workflow is analyzed as typical business collaboration.The research results of this text in web service collaboration frame and actual effect algorithms provide some new methods for applying the service collaboration technology, and improving its actual effect.
