Abstract: A network disaster-tolerant system is designed and realized, it adopts two levels disaster-tolerant system structure: network service system disaster-tolerant and network storage system disaster-tolerant, and integrates the network security mechanism with disaster-tolerant mechanism. The whole system has strong ability of system protecting and disaster tolerating, and improves the quality of system services. By system testing, the functions and performance of this system has achieved design goals, and can satisfy the demands of the network disaster-tolerant system.
