摘　　要：在云资源共享服务模式中,为实现云资源的多维度查询,提出一种基于P2P网络的云资源多维查询算法。在结构化对等网络的基础上设计一种分层的云资源网络拓扑结构。首先对云资源的属性和属性值分别进行编码,结合云资源多维发布策略实现了云资源多维查询;然后给出了该算法的查询效率分析和稳定性分析。实验结果表明,该算法能快速高效地实现云资源多维度查询,并且不会随着查询维度数和网络节点数的增加而产生较大的查询时延。In cloud resources sharing service mode, in order to realize the multidimensional queries of cloud resources, this paper proposed a cloud resources multidimensional queries algorithm based on peer-to-peer network. This algorithm designed a layered cloud resource network topology based on peer-to-peer network. Firstly, it encoded cloud resources attributes and at- tribute values respectively, and combined the cloud resources multidimensional release strategy to realize the cloud resources multidimensional queries. It presented queries efficiency and stability analysis of the algorithm. The experimental results show that this algorithm realizes multidimensional query fast and efficiently, it will not produce larger query delay with the increase of query dimension and nodes.
