摘要
对于Web服务组合来说,组件服务的可靠性和一致性是非常重要的要求,然而传统面向Qo S的组合方法中并没有考虑到组件服务的事务约束。文章提出了一种利用Web服务事务属性进行服务选择的方法。在该方法中定义了Web服务的事务属性和反映用户事务需求的冒险度,建立了事务驱动的服务选择有限自动机,并用实验证明该选择机制是有效的。
Reliability and consistency are most important requirements for Web service composition. However,the conventional Qo S- aware composition approaches don＇t consider the transactional constraints during the composition process. This paper addresses the issue of selecting Web services according to their transactional properties. Transactional attributes and risk are defined for Web service,and a transaction- driven finite automaton of service selection is proposed. Experimental results show that the selection mechanism is effective.
