Web service是目前计算机科学技术发展的一大趋势,随着功能相同的web服务的部署不断增加,许多研究人员提出了各种各样的web服务选择系统,这些系统主要用来自动实现服务的排名以及在大量候选web服务中选取最优的服务,另外一些研究人员则将其用于解决web服务随时间和与其他web服务的竞争而不断变化的动态环境。然而,这些系统仅仅能够实现最优服务的选择,面对web服务已被移除或者在实时系统中在不改变客户端应用程序的情况下的连接失败问题等故障情况,这类系统并不能提供一个直接的有效解决方案。在本文中,我们提出了一种新的web服务自动监控系统,它主要完成两方面任务：第一个任务是在动态的环境中,根据用户的请求选择基于QoS标准的最优的web服务;第二个任务是利用a.ent技术的优点来管理和监督web服务和客户端之间的通信。这通过自动服务方案（重定向或者用基于QoS标准的最优候选web服务替换）确保了在连接失败或者服务被移除的情况下服务传递的可靠性。
