摘要
Internet环境中大量的闲置资源为用户获得高质量网格服务提供了物质基础。但是资源的分布性、动态性和异构性的特征,以及用户对服务偏好的多样性和难以衡量性,使得对服务质量的评价非常困难。开发了一个网格资源管理调度系统平台,用多A-gent构件实现了对网格资源的评价与调度。为了提高网格服务质量,在综合考虑用户的多维Qos偏好和网格资源固有特征的基础上,把层次分析法引入网格资源的Multi-Qos评估模型,建立了以资源可用性能、价格、数据传输性能、安全性和可靠性为评价准则的综合评价模型。并通过对算例的评价结果,说明该方法的有效性和合理性。
There are large scales of idle resources on Internet that can be used by grid technologies.But the characteristics of grid resource such as distributed,heterogeneous,and dynamic make it more difficult to build the grid platform and evaluate the ability of the available sources Qos.A component-based resource management system is presented and a Multi-Qos evaluation model is proposed.The performance,price,throughput speed,reliability and security of resource are regarded as the criteria in the model.Samples have been done for the model and results show it reasonable and effective.
