摘要
采用阀值来控制复制副本数量的设想,对基于阀值的服务器主动复制策略进行了分析,并用Java语言设计实现了一种动态复制方法,其中考虑了网络和节点的负载动态变化对复制产生的影响.该方法可以较好地控制复制副本数量,降低副本一致性维护的代价.
In the distributed systems, replication is a key technique to its usability, fault - tolerance as well as efficiency. Threshold value is adopted to control number of duplicate. Initiative server replication with threshold is then analyzed. A dynamic replication method is realized by Java, which takes load variety of net and node into consideration. This method can control numbers of duplicate and reduce maintenance cost of coherence.
