| Abstract: | With the trend that data information has become the most important resource,the high availability and disaster tolerance of Network Information System become a pressing need.How to construct remote disaster tolerant system is an important problem in the network information system area.First,the paper introduces the basic concept of disaster tolerant,the categories and main performance indicator of disaster tolerant system,then analyses its key technology and selective principle.Finally,a remote disaster tolerant system based on Internet has been presented,which adopts two levels disaster-tolerant system structure: network service system disaster tolerant and network storage system disaster tolerant. |
