| Abstract: | 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. |
