摘　　要：利用面向方面编程(AOP)技术从静态结构和动态行为两个方面来建模网格服务质量。把服务质量QoS关注从系统的各个模块中单独分离出来,形成一个独立于系统核心组件的QoS方面,然后把设计好的QoS方面根据需要重新织入系统,与系统的核心组件一起实现系统。模型从系统的类图、状态图和QoS方面的隐含织入等几个部分来建模网格QoS方面,并用一个COBRA事件服务系统的例子来说明这种建模方法。该模型更好地提供网格下QoS保证,分离了QoS关注,提高软件重用性。Grid could be modeled by using aspect-oriented programming technology based on static structure and dynamic behavior.QoS requirements could be separated from the systems and expressed as a QoS-aspect independence of the core component,and the QoS-aspect could be woven into system with the core component to compose grid system based on the aspect-oriented technology only when needed for a particular application.Grid system could be modeled from the class graph diagram,statechart and weaving of the QoS-aspect,besides a COBRA event service system case was given as an example.The model provides QoS guarantees of the grid better,separated the QoS concerns,and improves the usability of the software.
