利用基于UML的面向方面编程(AOP)技术来建模实时系统,结合传统的网格QoS结构模型,把QoS关注从系统中抽象为一个独立于系统的QoS方面,从结构建模、行为建模、方面织入以及代码产生几个方面实现面向方面的建模方法.更好地提供网格环境下QoS保证,分离了QoS关注,提高软件的重用性。
Real-time systems can be modeled by using aspect-oriented programming(AOP) technology based on UML. Based on classic grid QoS archtechture models, QoS requirements can be separated from the systems and expresses as a QoS-aspect independence of the systems.It can be modeled from static structure, dynamic behaviors, weaving of time-aspect and genarating of codes, it can offer better QoS assurance in grid environment, separates QoS concerns, and improves the usability of the software.
