57 Research on Replicas Consistency Strategies Based on Optimization Replicas Chain in Cloud Storage

Replicas consistency strategies is an important aspect of ensuring the data is 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 maintained the replicas chain, and has analyzed the process of maintaining replicas chain. The simulation results show that the strategy can effectively reduce network redundancy and can timely update all replicas data of target data.
