摘要
由于突出的灵活性,对流程复杂度较小,节点分散的业务流程的快速适应能力等,建立P2P的工作流引擎成为工作流研发的一个热点方向。P2P环境下构建工作流系统必须解决好节点和工作流参与者的关系等一系列关键问题。给出一套完整的P2P工作流管理系统实现方案,在结合实际工程经验的基础上,分析了每个节点的行为特性,同时根据几种不同的流程运转方式提出了两处XPDL的扩展和3种不同的流程执行的算法,以使XPDL满足P2P环境的要求,并加快流程运转的速度。
Building the workflow systems on the peer-to-peer networks is a hot topic in workflow research. Because of it is adaptive to some small workflow and small business process. The key aspects of building workflow systems on P2P networks are solving the relationship between the peers and the participants. A complete implementing method of P2P workflow management system is represented, every node＇s characters is analyzed, and two changes of XPDL and three different algorithms of the process transferring are proposed, in order to make the XPDL suitable for P2P environment and speed the transferring.
