在攻击、故障和意外事故存在的情况下,可生存的网络系统仍然具有提供连续、可靠的网络服务的能力.本文提出了构建可生存网络系统的方法,可以增强网络系统最重要的三个特性:抵御、识别和恢复,从而从整体上有效地增强了网络系统的可生存性.这种构建网络系统的方法使得网络系统的可生存性不再依赖于特定的系统组件,相应地保护了网络系统的应用.
Survivable network systems have the ability to provide continuous and dependable services in the presence of attacks,failures,or accidents, In this paper, we present a method for building survivable network systems. This method can enhance some important properties such as resistance,recognition and recovery for survivable network systems, thereby effectively improving the survivability of network systems. Furthermore,the presented method enables the survivability of network systems independent of one or several system components, and is of great benefit to the protection of those applications of network systems accordingly.
