摘要:
分布式资源QoS的评价是指导大规模分布式系统进行资源选取与组合的主要手段。文章针对现有分布式资源QoS评价模型采用与应用领域无关的评价因子来评价分布式资源,不能全面衡量资源使用者对分布式资源QoS要求的不足,提出了一种领域自适应的分布式资源QoS评价模型DAQoSE(Domain-Adaptive QoS Evaluation Model)。该模型可支持针对不同应用领域的QoS评价因子动态定制。实验结果证明,该模型的评价结果优于其它评价模型,能有效应用于分布式系统资源管理、资源调度等分布式应用系统中。

Abstract:
The accuracy of QoS evaluation is the key to selecting resource from many available ones which provideoverlapping or identical functionality for the distributed systems, but current QoS evaluation models evaluate re-source only according to common evaluation attributes and, thus, cannot meet the QoS requirement of resource re-questors.Aiming at this issue, this paper proposes a Domain-Adaptive QoS Evaluation Model for Distributed Re-source called DAQoSE (Domain-Adaptive QoS Evaluation Model), which supports customizing evaluation attributesdynamically.The evaluation of relevant experiments shows that this model gets more accurate evaluation results incomparison with others.This model can be used in distributed resource management system and distributed resourcescheduling engine.
