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
