云计算环境下QoS偏好感知的副本选择策略
QoS preference-aware replica selection strategy in cloud computing
摘要
Abstract
A QoS preference-aware replica selection strategy for a kind of users with individual QoS sensitivity (IQS) constraints in cloud computing datacenters was put forward in advance. According to the QoS requirements of data services from IQS users, a novel three-dimensional QoS model of replica selection was introduced, and a QoS preference-aware algorithm based on analytic hierarchy process (AHP) named QoPA was proposed to deal with the IQS constraints. In order to evaluate the replica sites in datacenters and provide the best of them to the IQS users, an algorithm for replica selection based on fuzzy comprehensive evaluation termed FCE_RS was designed and implemented. Results of experiments show that the FCE_RS can serve the various IQS users in cloud computing very well by providing reasonable replica strategies effectively.关键词
