Abstract: Safety critical network determines the survival and the development of the safety critical system. With the change of safety critical system’s environment, survivability and real-time communication have become two crucial questions. This paper analyzes the structures of five kinds of safety critical networks and indicates the shortage of them. It proposes a new structure of survivability safety critical network based on fibre channel, and suggests a dual self-healing algorithm to reduce the recovery time and improve the rate of recovery.

Key words: safety critical network, survivability network, dual self-healing algorithm
