基于QoS的自适应控制中间件研究与应用

Research and Application of Qos-based Adaptive Control Middleware

文章重点研究在自适应控制中间件支持下,Web服务组合执行引擎的QoS管理机制,设计了一个基于QoS的自适应控制中间件,并应用于Web服务组合执行引擎当中,以支持对服务请求的分级处理,实现了为不同等级用户提供区分服务的功能,为提高可变负载下单个执行引擎的高吞吐量和快速响应时间提供了一种有效的解决方案。

This paper focuses on the QoS management mechanism in web service composition execution Engine,which is supported by the self-adaptation middleware.The QoS-based adaptive control middleware is designed and used in web service composition execution engine,so as to support the stage treatment of service requests,thus its functions of providing differentiated services for the users of different levels have been realized.Besides,an effective solution has been proposed to enhance throughput and response time of single execution en-gine under the condition of changing loads.
