摘要
针对大规模的云资源共享,单关键字查询技术已不能满足用户对资源的查询需求这一问题,研究了如何在资源共享中实现多维查询。在结构化P2P网络的基础上,通过对资源属性和属性值采用不同的编码方式,建立一种适用于多维查找的分层网络结构,结合多维度的资源存储和发布策略,实现了一种适用于云资源共享的多维资源查找方法。实验表明,该方法具有很好的可扩展性和准确性。可以快速有效地实现多维查找,也极大地扩展了对等网络技术在云计算服务中的应用。
The cloud computing provides more and more large-scale resource to share.The technology of single-keywords querying can’t meet the demand of user’s searching.This paper proposed a design of multidimensional queries on resource sharing.Based on P2P network,encoding resource attributes and attribute values in different way,it established a hierarchical network contracture of multidimensional lookup.And adopting a multi-dimensional resource storage and release strategy,it achieved a quick and effective multidimensional way to search resources in a cloud application.In the experiments,the method demonstrates good scalability and accuracy.It can achieve the multi-dimensional search quickly and effectively,and greatly expand service in peer-to-peer network applications in the cloud.
