Replication strategy based on file-partition for P2P network
P2P网中基于文件分片的副本建立策略*

In large scale of P2P network, in order to get high data availability, to actively replicate data to other nodes is used to increase data redundance. To reduce replication cost, it was better to use a file-partition based replication strategy. Data file could be partitioned into pieces which would then be distributed and copied within a collection of node selected beforehand. It can sufficiently use the network bandwidth and obviously reduce the replication time cost .
