Abstract: 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.
