基于QoS的Web服务发现与组合框架

摘要

A discovery and composition framework based on QoS is presented. In the framework discovery and composition based QoS is divided into six phases of receive of use requirement, services discovery, design of function flow, selection of aware-QoS services, executing of composition, evaluation of result. The framework can support automatically construction of the function flow and global optimal selection of the web services based on QoS.%本文提出了一个全面支持QoS的通用Web服务发现与组合框架.该框架将基于QoS的服务发现与组合过程分为接收用户请求、服务发现、功能流程设计、全局QoS服务选择、服务组合执行、组合结果评估6个阶段,能够支持服务组合中功能流程的自动构建和QoS全局最优的Web服务自动选择.
