摘要:

基于异步协议兼容中的可同步条件,对异步消息通信环境中的服务交互进行接口兼容分析,提出一种异步环境下的接口兼容分析方法,通过这种方法,可以判定两个接口之间的异步交互行为是否是一致的,从而可以应用于接口的匹配问题和服务组合的设计时验证,保证最终获得的组合协议也满足可同步条件。

Abstract:

Although Asyn message interaction is undecidable, the asynchronous interaction behaviors equal to synchronous if the interface peers hold synchronizable condition. Based on this theory a new method is proposed to analyze interface compatibility of E-service under asynchronously communicating environment. Through checking synchronizable condition as well as customization on compo sited interface automata, this method also supports the asynchronous interaction check between two service interfaces. Meantime, when applied service composition it can assist composer to guarantee the correctness of composition in term of synchronizable condition.

Key words: interface compatibility, asynchronously communicating, composition, session-oriented E-service, Finite states machine, Web service
