A Market-based Strategy to Replica Selection for Data Grid
一种基于市场机制的数据网格复制选择策略

In this paper, a market-based strategy is presented to select replica in data grids, which is based on equilibrium theory and which realizes the replica selection strategy. Firstly, a market model of replica selection in data grids is given, in which the utility function is used to characterize the transmission between the user agents and the data replica. Then the replica generation and replica selection automatically are given, which are based on the law of supply and demand. Finally, the time cost and space cost to the algorithm of the strategy is analyzed.
