| 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.

| Abstract: | 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. |
