摘要
提出了一种新的动态副本管理机制。该机制根据文件受欢迎的程度,增加受欢迎程度高的文件副本数量,选择高性能节点存放文件副本,从而使系统自动调整文件副本数量以及副本存放位置,平衡节点负载,提高文件的可用性。
This paper presents a novel dynamic replication management mechanism called ＂DynRM＂. In DynRM, the system distributes the file replication according to the degree of the file popularity, and selects the high capacity node to store the popular replication. The system adjusts the location and amount of replication according to the replication strategy in order to balance the node load and improve the file availability.
