| 摘 要： | 如何改进现有服务发现模型使之适应动态可变的服务运行环境并选择最符合用户需求的Web服务正在引起研究领域关注.提出了一种基于策略的可控服务发现与动态路由模型(P-WSDRM).该模型支持抽象服务、服务实例和服务发现者的属性定义,支持携带属性描述信息的服务发布与发现,引入了策略判定机制,支持服务发现者基于已定义的策略进行服务发现和实例路由.目前已经于Linux平台和目录服务实现了该模型的一个原型系统.

| Abstract: | How to improve the existing service model to adopt the dynamic changing service running environment and select web services that can best meet the requirements of consumers is an ongoing research direction in web service community.A policy-based model for controllable service discovery and dynamic routing called P-WSDRM is proposed.A set of attributes are defined in the model to describe the Abstract service,the service instance and the service requester,which will support the service publish and discovery with attributes constraints.A policy determination mechanism is used to allow service discovery and instance routing based on beforehand defined polices.A prototype based on Linux platform and directory service is implemented. |
