基于QoS的Web Services发现

出于对组合Web服务中QoS管理的目的。对WSDL进行扩展提出了新的服务描述语言，并扩展了Web服务的角色，提出了服务代理角色，在传统的Web Services架构的基础上进行扩展给出了一个改进的Web Services架构，最后给出了原型系统的实现方案和试验；并对试验结果作了分析，得出了改进后的Web service架构在服务发现时性能、效率优于传统的Web services架构。

Web Services Discovery Based on QoS

This text,from the purpose to make up Web service QoS management, and the demand to set out QoS which services management, have proposed a new service describe language that WSDL is expanded , and has expanded the role of Web service,by adding the agent role. We expand and provide an improved Web Services Architecture on the basis of traditional Web Services architecture, provide the realization scheme of the prototype system and test finally. We has done analysis to the result of the test, the result is that the improved web services architecture is better than the traditional web services architecture in some aspects.
