Abstract: The definition of survivability of network was discussed and a new definition on the premise of staying alive was made. The guiding principle of biological immune system to the network survivability was analyzed, and a method for the second development of survivable network system was presented. The survivability of system was controlled by many immune units which were autonomous and distributed. Each immune unit consisted of four logical parts: detection, identification, prevention, and self-adaptation and evolvement. The model, classification and implementation of the immune unit were given. The design is of certain distribution and self-adaptation.

Key words: survivability, immune mechanism, network security, self-adaptation
