Abstract
Replica technology increases the reliability and availability of data by increasing the redundancy of data in the system. The existing replica replication algorithm only depends on the access traffic of the node when selecting the replication node, ignoring the non-cooperation of the node, resulting in a decrease in the utilization of the replica. This paper proposes an adaptive replica management policy PCA based on node reputation. PCA selects nodes with large query traffic and high reputation as replication nodes to ensure high query hit rate. Because PCA sets the copy according to the cooperation of the node, it avoids the waste of copy caused by setting the copy on the non-cooperative node, and guarantees high copy utilization.
