Dong Jian-quan · Jisuanji gongcheng · 2008
How to use a dynamic replication management mechanism to improve the usability and reliability of the data in the network becomesthe hot spot of research in recent years.This paper presents a kind of dynamic replication management mechanism based on the trend forecast byusing the smoothing arithmetic of time sequence in the economic area to forecast the hot file, and using three different strategies to place, delete, andreplace the replica dynamically.It can increase the hit rate in the resource searching efficiently in P2P network, decrease the cost of the wholenetwork, and balance the load of every node in the network through simulation experiments and the analysis of its data.
