从汶川地震看信息通信网络的容灾性

Disaster recovery of the information communication networks seen from Wenchuan earthquake

汶川地震对当地信息通信网络造成了极大的破坏,文章首先提出了完善网络结构,提高网络防御灾害能力的方法,然后介绍了如何建立异地容灾系统,以提高信息网络的容灾性,最后探讨数据容灾系统技术方案。

The Wenchuan earthquake has caused great disaster to the local information communication networks. Firstly, this paper puts forward the methods to perfect the network structure and enhance the disaster-defending ability of the network. Secondly, it introduces the way to build the disaster recovery system between different places so as to increase the disaster recovery of the information network and in the end, the technical scheme of the data disaster recovery system is discussed.
