本文比较了不同的网络系统可生存性的定义并指出了其中最具本质特征的定义,介绍了网络系统可生存性研究的进展,包括可生存性的分解和可生存系统的特性,定量评估,体系结构以及设计方法,回顾了可生存性研究中存在的问题,探讨了以后的研究方向。
Different definitions available of network system survivability are compared and the one essentially most accurate is pointed out.The research achievements of network system survivability are presented,including the decomposition of survivability and the properties,the quantitative evaluations,the architecture,and the design methods of survivable network systems.The unconquered difficulties of survivability research are reviewed and the possible further development directions are also discussed.
