Load balancing study in cloud storage based on dynamic replica technology
基于动态副本技术的云存储负载均衡研究

For the load balancing of cloud storage system, this pape provided a multi-time windows load balancing strategy which had three time window with different size, this strategy could achieve the load balancing of storage nodes and replicas. It designed new method to statistic the heat of files, it associated the heat of a file with time sequence, which could effectively avoid the creation of replica because of burst of file access in a brief moment. The experiment indicates that multi-time windows load balancing strategy can effectively reduce the response time of I/O access.
