Abstract: Study of system architecture is the base of design and implementation of any practical system. This paper defines the survivability architecture and correlation concepts of network information system and principles, analyzes the run mechanism of survivability systems and explains the effect of survivability specialties. The survivability architecture of 3+2 model is presented. Practices show the architecture is effective.

Key words: network information system, survivability, run mechanism, architecture

摘要：

系统体系结构的研究是设计和实现任何实际系统的基础。该文对生存性网络信息系统的体系结构及其相关概念进行定义，明确生存性网络信息系统体系结构的设计原则，分析生存性网络信息系统的运行机制，说明生存性特性的作用，并构建3+2模式的生存性网络信息系统体系结构。实际运行结果表明了该结构的有效性。
