| 摘 要： | 可生存性是关键信息系统的重要特性.该特性使得系统在故障、攻击存在的情况下,仍然能够提供一定水平的服务.本文提出了一种通过网络配置切换实现层次型服务网络可生存性的方法,并着重论述了该网络配置切换的各种操作所组成的系统在应对各种可能出现的故障或攻击时的完备性.形式化地定义了层次型服务网络可能遭遇的故障和攻击,并针对每一故障和攻击,说明通过某一个或几个操作,总可以使层次型服务网络最大限度地继续提供其基本服务.

| Abstract: | Survivability is a crucial characteristic of critical information the systems.It ensures that these systems can provide some level of service in the presence of various types of failures or attacks.In this paper,a network configuration-switching method used to achieve survivability is proposed for hierarchical service network and the completeness of the system composed of operations in the network configuration-switching is stressed.The failures and attacks,to which the hierarchical service network may be s... |
