摘　　要：为提升光纤通信传送网在复杂对抗环境下的抗毁韧性,系统构建了物理网络-逻辑网络依存模型,首次提出包含脆弱因子、恢复因子、反应时间和恢复时间的四维抗毁韧性指标体系。通过数据归一化加权求和方法建立量化评估模型,结合某区域光纤通信传送网实例,实证分析主备路由规划、反应时间及恢复时间对抗毁韧性指标的影响。研究表明:采用主备路径负荷分担策略可使抗毁韧性评分提升16分;反应时间缩短至2 min可提升评分5.5分;恢复时间延长至60 min则导致评分下降5分。To enhance the survivability resilience of optical fiber communication transmission network in complex adversarial environments,this paper systematically establishes a physical-logical network interdependence model and,for the first time,proposes a four-dimensional survivability resilience evaluation framework incorporating vulnerability factors,recovery factors,response time,and restoration time.A quantitative evaluation model is established using data normalization and weighted summation methods.Through empirical analysis of a regional optical fiber communication transmission network,the impacts of primary-backup route planning,response time,and recovery time on survivability resilience metrics are investigated.The results indicate that adopting a load-sharing strategy for primary-backup paths increases the survivability resilience score by 16 points,reducing the response time to 2 minutes improves the score by 5.5 points,while extending the recovery time to 60 minutes decreases the score by 5 points.
