Research And Implementation Of SD-Anycast Routing Protocol

To share the information by using the resources of enterprises and avoid the "information isolate island" for the enterprise are the destination of the EAI. Close coupling in traditional integration brings many problems such as about extensibility, maintenance and high cost. Web service has been the trend of EAI, which has the characteristic of simpleness, flexibility, good extensibility, scalability and open standard. However, there is no management mechanism of state in traditional web service,witch make it difficult to be adaptive to variety in businesslike web application.With the development of Grid techlonogy and based on web service,OGSA/WSRF bring the state into Web service to solve these problems.Beginning with description the neccessary of enterprise application integration, we analyse the implementation and technology of several traditional EAI,then bring forward an architecture based on OGSA/WSRF uesed to application integration.Then describe the means by which the stateful resource associate with the web service and the choice of host environment.Our research focus on design and implementation of WSRF in J2EE environment,including WS-ServiceProperties, WS-ResourceLiftime,WS-ServiceGroup,WS-BaseFaults,WS-Notification, modeling in stateful resource with Web service. Finaly, as the example, the use of architecture based on OGSA/WSRF in modern ship management information system, verify the application value of EAI based on OGSA/WSRF.
