云计算环境下支持多属性查找的混合对等网络

A Hybrid P2P Overlay for Multi-attribute Queries in Cloud Computing

针对云计算环境下,云资源的多属性查找问题,设计了一种混合结构的对等网络。该网络采用多星形拓扑结构,将云资源以统一的编码方式规范化之后部署到该网络上,可较好地实现多属性查找。文中描述了多属性查找算法,分析了网络性能,该网络旨在降低资源查找的跳数,因此文中主要分析网络查找跳数。实验表明,资源查找跳数得到优化,达到了预期效果。

To resolve the multi-attribute queries of cloud resource in cloud computing,a hybrid P2 P overlay is proposed in this paper. The overlay is based on the combination of multi-star topology. Multi-attribute queries will be achieved if the normalized cloud resource is deployed to the overlay. In the paper,the algorithm for multi-attribute queries and the performance of the network are described. The overlay is designed to reduce the number of hops in resource searching,so the analysis to the number of hops is the point in the paper. The experimental results show that the number of hops in the overlay is reduced as respected.
