基于OLAP的副本选择体系结构OLAPRES

OLAPRES:Based on OLAP Replica Selection Architecture

针对当前副本选择算法处理时间随副本个数增加而急剧增加的问题,提出一种基于OLAP技术的副本选择体系结构OLAPRES,利用OLAP技术中的数据预处理和快速查询功能,使大量副本中的快速选择成为可能并描述了基于OLAPRES副本选择的工作流程.

A replica selection architecture based on online analytical processing technique is proposed and called as OLAPRES; it makes it possible that a lot of replicas can be selected efficiently by the basic online analytical processing functions of data preprocessing and rapid retrieve; the workflow of replica selection in OLAPRES is depicted finally. Compared to other replica selection architectures, the architecture of OLAPRES has advantages of fastness, scalability and flexibility.
