Abstract: To eliminate overlapping data spreading repeatedly and nonupdated data spreading, and to replicatemulti-intersected copy in parallel links, based on the state of copy replication on every node in parallel links, the following three strategies were proposed: twice-spread once-replication, twice- spread once-thruput twice-replication, and parallel-spread twice-thruput three-time-replication. The mechanism of the strategies is thatmulti-intersected copy is disassembled and spread followed by reassembly and replication.
