Agent技术在Web服务中的应用探讨

Web服务是一组采用面向服务的体系架构的基于标准的Web协议的软件构件,而Agent是一种在某个环境中自主行动以实现其设计目标的智能化软件实体.Web服务与多Agent系统(MAS,Multi-Agent System)在架构、范例和技术方法等方面具有很大的相似性.Web服务的可信性是未来计算机软件发展关键的问题,实现Web服务在分布式环境下的协同式测试具有一定的挑战性.本文在探讨Web服务与Agent技术的共性的基础上,分析并总结了Agent技术在Web服务中的应用.针对Web服务测试的开放性、协同性、动态性和不确定性等特点,结合Agent系统的自主性、反应性、适应性和社会性,本文提出了一种基于MAS的Web服务测试框架(MAST,Multi-Agent-based Service Testing),并对其关键技术进行了探讨.

Applying Agent to Web Services: a Survey

A Web Service is a self-contained software component that reflects the Service-Oriented Architectural(SOA)approach,enabling cross-platform integration by standard Web-based protocols.While an Agent is an intelligent software entity that is capable of independent action providing controlled access to shared services and resources.Web Services share many similarities to Multi-Agent System(MAS)in architecture,paradigm and technology.The trustworthiness is a key issue in the tremendous growth of Web Services.And collaborative distributed test for Web Services becomes a great challenge.This paper is going to discuss the commonness of Web Services and Agent,and briefly summarize how Agent can be utilized to add value to Web Services,which promotes cross-fertilization of techniques between these two areas.Due to the open,dynamic and collaborative nature of Web Service test,regarding the autonomy,reactivity,pro-activity and social ability of Agent,this paper proposes a Multi-Agent based Service Testing(MAST)framework,and discuss its key technology.
