摘要 为解决现有的quorum系统节点没有差异、数据读取延迟较大、存储利用率低等缺陷,提出了一种新的基于特权分级的quorum系统。该系统借助代理动态调整各quorum,并按数据存储时段将各节点划分为不同的等级,此外还设计了相应的数据读写协议。通过系统性能分析表明,该方案具有读写高效性、存储可靠性及易于扩展等优点。

英文摘要 In order to enhance the efficiency of data access and resolve the problems of existing quorum systems, such as no differerce between the nodes, great latency in data access and low storage utilization, this paper presented a new quorum system based on privileges classification of all nodes. The system adjusted each quorum dynamically by means of the usage of proxy. Besides, divided the nodes of the system into different grades according to data storage time, and designed the corresponding data read and write protocols. As a conclusion of the system performance analysis, it shows that the scheme has the advantages of high data access efficiency, storage reliability, flex to be extended and so on.
