云计算下用户行为特征的服务选择策略

在云模型中,不同的网络资源被网络虚拟化抽象成为各种服务,这些服务经过进一步的组合后以服务组合的方式提供给终端用户。为保证用户能高效地选取服务,从用户体验质量的角度,分析云环境下用户访问服务的行为,利用其访问服务的偏好性,提出基于用户行为特征的服务选择策略。理论分析和实验表明,该策略能保证较高的性能及用户满意度,能为用户提供有效的选择方案。

Services selection strategy based on user behavior in cloud computing

In the cloud model, different network resources are abstracted into various services by network virtualization. After further combination, these services are provided to end users through service composition. To ensure that users can select services efficiently, this paper, with a view to Quality of Experience, analyses user behaviors of access to services in the cloud environment, exploits user preferences of access to service and then presents a service selection strategy based on user behavior. The theoretical analysis and experimental results show that the strategy can ensure higher performance and user satisfaction, and provide users with effective options.
