Research on replica placement strategy based on game theoretical analysis.

It's the requirement to research data replication strategies for improving the reliability and efficiency of complex network. We use noncooperative game theory to analyze the replica placement problem in the paper, and the model of replica placement in large-scale distributed network is proposed. Then we prove the existence of pure strategy Nash equilibrium in the model, and propose the replica placement arithmetic. The method in this paper is of reference value for improving the usability and efficiency of massive data, and the content is helpful to elevate network performance in large-scale distribution network.
