一种构建COTS中间件的自适应Web服务方法

AN APPROACH FOR COMPOSING ADAPTIVE WEB SERVICES OF COTS MIDDLEWARE

自适应Web服务运行在COTS中间件平台具有特别的挑战性。通过引入业务Web服务与自适应组件之间的管理代理,给出一种构建COTS中间件的自适应Web服务的解决方案。管理代理可以定制并利用现有的中间件机制无缝地集成到一个COTS平台。通过一个基于.Net WCF的Web服务应用来论证此架构。结果表明,该方案在性能和灵活性方面是有效的。

It is especially challenging for adaptive Web services running on COTS middleware platforms.In the paper,with the introduction of a management proxy between adaptive control components and business Web services,a solution of composing adaptive web services of COTS middleware is proposed.The management proxy can be customised and seamlessly integrated into a COTS middleware platform by leveraging the existing middleware mechanisms.Finally,an example of Web service application based on.Net WCF demonstrates the architecture.The results validate that our solution is efficient in terms of performance and flexibility.The results validate that the solution is efficient in terms of performance and flexibility.
