摘要
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 and commercial application environment,it is an important link to protect user QoS requirements,and optimize service efficiency and effectiveness of system resource.For ensuring the balance of QoS requirements between two sides of supply and demand,a method of estimating the QoS expectation for users is proposed in the paper,which can compute a set of balanced QoS parameters value in view of the QoS ability of provider based on the principle of effectiveness.The service selection can obtain a higher efficiency of utilizing by using the proposed method.An actual example with analysis shows that it could reliably estimate a set of effective QoS expectations.
