Abstract

The WS-Resource framework (WSRF) was proposed as a reengineering and evolution of OGSI to be compatible with the current Web services conventions and specifications. Although WSRF separates state management from the stateless web service and provides a mechanism for state management, it still has some limitations. The tight-coupling between web services and their resource factories restricts the scalability. When the repository of stateful resources fails, stateful web services can not work. In this paper, we propose a new state management framework which is called State Management Web Service Framework (SMWSF) and implemented on Microsoft .NET framework. SMWSF provides reliability, flexibility, scalability, and security. SMWSF provides migration of state information and the service requestor can control the location of the repository of stateful resource. We also implemented a prototype system and conducted comparison experiments to evaluate performance.
