移动终端云存储技术研究

摘要

By analysis of HDFS and Dynamo, in this paper, one dynamic consistency Hashing algo-rithm is introduced to classify and deal with different object groups. According to the comprehensive dis-patching of storage cost of each storage node, the optimal storage node is selected to realize the mobile terminal cloud storage access. The simulated experiment shows that the multi-copy mechanism of cloud storage system can effectively improve the efficiency of the system and, when the mobile terminal makes a request, the most recent copy can be selected to save time.%通过分析HDFS和Dynamo,该文引入动态一致性哈希算法,对不同对象组实现分类处理,根据各个存储节点的存储代价综合调度,选择最优存储节点实现移动终端云存储访问.经仿真实验验证:云存储系统的多副本机制能够有效提高系统效率,当移动终端发出请求时,选择最近的副本能够有效节省时间.
