【摘要】 传统C/S体系结构的工作流系统通常存在服务器端的资源瓶颈,现有的少数几个基于P2P的工作流系统没有利用W eb服务的优势。针对以上不足,提出了一个基于P2P网络的W eb工作流管理系统体系结构。系统引入通知机制实现工作流的分布式管理,工作流中活动由W eb服务实现,工作流成为一个能够在Internet上调用的服务。系统克服了中央服务器的缺陷,具有较强的适应性、扩展性。更多还原

【Abstract】 The workflow systems with conventional C/S architecture often have resource bottleneck in server.The few currently existing P2P based workflow systems fail to utilize advantage of Web services.To avoid above shortages,this paper presents the architecture of a P2P Web workflow management system.It imports a notification mechanism to realize the distributed ma-(nagement) of workflow.Activities in workflow are implemented with Web services and workflows become Web services which could run on Internet.It overcomes the defect of the central server,has stronger adaptability,scalability,flexibility and better performance.更多还原
