摘　　要：面向网络化控制的自适应中间件需要为上层控制业务应用提供随需定制的网络服务质量保证。现有的网络服务模式大多采用尽力而为的模型,多个服务协作使用资源时,性能和效率也容易造成降级。为此提出了面向网络化控制的自适应中间件设计了网络服务质量(Quality of Service,QoS)策略框架。最后设计了构件部署仿真,对计算资源的动态不确定性变化对己建立的服务构件的适应性满足程度进行评估,仿真结果表明,算法资源消耗较低,对不同的业务场景有更好的适应性,从而验证了QoS策略框架的有效性。Networked control oriented adaptive middleware for the upper control business application provides on-demand customized network service quality assurance. Existing network service models mostly adopt the best model,when multiple services use resources collaboratively,the performance and efficiency can cause drop easily. In this paper,we designed for a class of networked control oriented adaptive middleware for Quality of Servic,network Quality of service（ QoS） policy framework,including QoS semantic model,QoS service model and component deployment algorithm. Finally,we designed the component deployment simulation experiment,to evaluate the satisfaction of change of dynamic uncertainty of computing resources to establish the service. The simulation results show that using the algorithm,the resource consumption is low,the adaptability to different business scenarios is better,which verifies the effectiveness of the QoS policy framework.
