基于弱同步的服务交互适配方法

Service interactions adaptation approach based on weak synchronization

为了使各种行为或接口描述异构的服务能正确交互,提出了一种适配方法。该方法以消息映射规则描述消息和消息参数之间的映射关系,以标签转换系统来描述服务的行为,以同步向量来描述服务之间的交互,以弱同步的方式来控制服务之间的交互过程。通过算法和弱同步的思想解决了标签转换系统中无法实现消息存储转发功能的问题。实验结果表明,该方法不仅能解决消息和消息参数之间的基调失配,还能解决行为失配中未指定的消息接收失配。

Aiming at interactions among many Web Services with heterogeneous interfaces or business protocols,an adaptation method was proposed.In this method,the mapping relationships among messages or message parameters were described by the message mapping rules,the behaviors were described by labeled transition system,the inter-actions were described by synchronous vectors,and the interaction processes were controled through weak synchro-nization.Storing and forward messages in Label transition system was realized by the proposed method together with the weak synchronization conception.Experimental results revealed that the approach could resolve not only signature mismatches among messages and message parameters but also behavior mismatches of unspecified recep-tion.
