RESEARCH ON REPLICAS CONSISTENCY STRATEGIES BASED ON OPTIMIZATION REPLICAS CHAIN IN CLOUD STORAGE

摘要

Replicas consistency strategies ia an important aspect of ensureing the data available.After Analyzing and summarizing relevant academic research,this paper has proposed the replicas consistency strategies based on optimization data copy chain, has created the replicas chain and maintenanced the replicas chain,and has analysised the process of maintenancing replicas chain. The simulation results show that the strategy can effectively reduce network redundancy and can timely update all replicas data of target data.
