基于目录哈希树的电力通信网络数据容灾备份

Data disaster recovery backup of power communication network based on directory Hash tree

为了在电力通信网络中快速存储已输出的信息参量,从而缩短数据恢复所需的消耗时间,提出一种基于目录哈希树的电力通信网络数据容灾备份方法。根据目录哈希树定义原理,对电力通信网络中的数据转存节点作出部署,完成通信数据的负载均衡处理,实现基于目录哈希树的容灾备份组网。借助Windows存储栈结构,设置容灾备份服务对象的所属格式,再借助所有已知条件,计算容灾备份频率指标的具体数值,完成基于目录哈希树电力通信网络数据容灾备份方法的设计。实例分析结果表明,在目录哈希树原则支持下,数据容灾备份方法在不同场景中均能快速存储已输出的信息参量,对于缩短数据恢复耗时具有较强促进作用。

In order to quickly store the output information parameters in power communication network and shorten the consumption time of data recovery,a data disaster recovery backup method based on directory hash tree is proposed in this paper.According to the definition principle of directory hash tree,the data transfer nodes in power communication network are deployed to complete the load balancing processing of communication data,and realize the disaster recovery backup networking based on directory hash tree.With the help of Windows storage stack structure,set the format of disaster recovery backup service object,and then calculate the specific value of disaster recovery backup frequency index with the help of all known conditions,so as to complete the design of data disaster recovery backup method of power communication network based on directory hash tree.The example analysis results show that under the support of the directory hash tree principle,the data disaster recovery backup method can quickly store the output information parameters in different scenarios,which plays a strong role in reducing the time-consuming of data recovery.
