【Abstract】 A dynamic configuration framework for middleware Quality of Service(QoS) based on reflection is proposed.On basis of dynamic sensing environment change,QoS metric function and Climbing Algorithm(CA) are used to search optimal configuration,and dynamically adjust system parameters to meet users’ service demands by means of reflective mechanism,so that system performance optimization can be achieved online.Simulation experimental results show this framework is effective.更多还原
