%X Data replication is a key issue and an optimization technique of achieving better access times to data and fault tolerance.A replication strategy based on a double auction mechanism was discussed to solve the problem that the replication strategy cannot be adapted to the high autonomy and dynamics of data.Firstly,a double auction model was described.Secondly, a continuous double auction protocol's implementation based on the distributed Continuous Double Auction Protocol(CDA) and Zero Intelligence Plus(ZIP) bid strategy were given.Finally,simulation with Optorsim was carried out to the replication strategy and model. The experiment results show that,compared with the one-side auction,the proposed model and strategy provide less operation time and higher network use rate, better Computing Elements(CE) and Storage Elements(SE) utilization ratio.
