Research And Development Of Grid Services Based On WSRF.NET

Because of the increasing demand for high-performance, a single computer could not solve large scale problems.Grid, whose Features are Heterogeneous, synchronous, resource sharing and Collaborative, can solve this problem. Grid forms a new generation of Grid architecture OGSA (Open Grid Services Architecture), by combining the latest Web Services technology.OGSA-based Grid Service, by providing a interface with clear specification, enables information, resources and applications'integration and sharing. OGSI specification has developed WSRF, which mix Grid Services and Web Services. WS-Notification specifications, as the basis for Web service specification, is commonly used in distributed asynchronous transfer mechanism, create a standard process of event-driven system in a Web services environment.WSRF.NET software provides a fully support for WSRF and WS-Notification. In this paper,this open-source platform is researched.By introducing the concepts and technologies related to Grid Services, constructed test environment based on the Grid, and described in detail the programming technology based on this platform.For relieve the issue that performance of stock company's server can not afford the large flow of data access when the server market is buy. WSRF.NET-based stock quote Service Grid applications is designed. In this paper, feasibility and superiority of Grid Service based on WSRF.NET service is verified. Laid the foundation for further application of Grid Servces.
