在网格计算商业应用环境中,保障用户服务质量(QoS)需求和服务使用效益以及优化系统资源效能是一个重要环节.为保证服务供求双方QoS需求的均衡,提出了在QoS参数匹配时,对用户QoS期望值进行估算的方法.该方法根据效益原理,针对服务提供方的QoS能力,估算出一组均衡的QoS参数值,为服务选择提供依据,使用户能获得较高的服务使用效益.实例分析表明,该方法能可靠地估算出有效的QoS期望值.
In grid computing business application environment, it is an important link to guarantee the quality of service (QoS) demand and service usage efficiency and optimize system resource efficiency.In order to ensure the balance of QoS requirements between service providers and consumers, User QoS expectation.According to the principle of benefit, the method estimates a set of balanced QoS parameters according to the QoS capabilities of the service provider, and provides a basis for service selection so that the user can obtain higher service usage benefits. Analysis shows that this method can reliably estimate the effective QoS expectation.
