中文摘要: 针对传统的集中式的服务发布、服务发现存在的问题以及服务工作流只能在流程定义阶段静态绑定服务的问题，提出了采用基于服务分类的三层chord来组织web服务的方法和逻辑工作流与资源层交互的模型。首先介绍了web服务分类模型，然后对结构化p2p资源层进行建模，并提出了逻辑工作流的定义方法，最后设计了流程匹配、服务发现、服务选择和服务绑定四个功能模块来实现逻辑工作流到可执行工作流的映射。
Abstract:For the problem of service publishing and discovery in traditional centralized mechanism and that of service workflow binding static service at flow design stage, this paper proposes a method of using service classification based 3-layer chord to organize services and the model of logical workflow interacting with resource layer. Web service classification model is introduced first. Then, structured p2p resource layer is modeled, and the method of logical workflow definition is introduced. Finally, four functional modules including process matching, service discovery, service selecting and service binding to realize the mapping from logical workflow to executable workflow are designed.
