摘要: 针对云计算环境资源动态性特点,给出了一种资源分配算法公平性动态度量模型——DFE (dynamic fairness evaluation)。模型引入了公平、效率和时间参数,通过将资源分配结果进行量化处理,定量地描述不同分配算法的公平性。首先考虑了云环境下的2种典型动态因素:节点资源需求动态变化和虚拟节点动态变化,并分别对这2种场景建立子模型,通过这2种模型导出了DFE。分析了2种子模型以及DFE,通过DFE对几种典型资源分配算法进行度量,验证了在资源需求以及虚拟节点动态变化的情况下,DFE能够有效度量分配算法公平性。

Abstract: Dynamic fairness evaluation framework (DFE) was given according to the dynamic features of resources in cloud environment. In DFE, the factors of fairness, efficiency and time were introduced, and the allocation results were processed into numeric values, which could measure the fairness of allocation algorithms quantificationally. Two typical dynamic factors in cloud environment are considered, dynamic resource demands of virtual nodes and dynamic quantity of virtual node number. Then, two sub-models are established for both of the dynamic factors, with which DFE is finally derived. Both of the sub-models and DFE are analyzed, and evaluated with several typical resource allocation algorithms. The experimental results prove that DFE can effectively provide a measurement for allocation fairness evaluation in the case of both dynamic resource demands and node number.
