中文摘要：
对突发毁伤条件下的网络性能进行实时监测,获取其动态变化曲线;在此基础上,首先依据网络业务的服务质量（Qo S）要求,科学设定性能参量的上、下Qo S边界值;其次构建网络可生存性的评价指标体系,分析了评价指标与网络性能参量之间的映射关系,并给出指标量化算法;最后结合突发事件的威胁度,对网络总体可生存性进行综合评价,实例分析表明,评价指标的计算过程较好避免了人为主观因素的影响,其评估结果更为客观、有效.
英文摘要：
Network performance parameters were monitored in real time under conditions of the burst damage,and its dynamic curve was got. On the basis,firstly,the upper and lower boundaries of performance parameters were set scientifically according to the quality of service requirements of network services; then,the evaluation index system of network survivability was built. The mapping relationship between evaluation index and network performance parameters was analyzed,and the quantitative calculation method of index was given; finally,the overall survivability was evaluated comprehensively according to the threat level of emergencies. Analysis shows that the proposed method is scientific and effective.
