摘　　要：对于具有超高抗毁要求的网络,如何通过增量规划配置方式部署资源以提升其业务的动态可恢复性,提出了一种面向双链路故障的组合式网络增长规划算法(简称CA-DF策略),建立了整数线性规划(ILP)模型,并进行了仿真计算。仿真结果表明:CA-DF策略能在添加尽量少的网络资源情况下有效提升业务双链路故障下的动态恢复率。With ultra-high invulnerability of the requirements of the network,how to use incremental deployment of resources in order to enhance their business planning configuration way dynamic recoverability,a combined network growth planning algorithm for dual link faults(CA-DF strategy)is proposed,integer linear programming(ILP)model is established,and a simula-tion calculation was carried out.The simulation results show that CA-DF strategy can effectively improve the dynamic recovery rate under dual-link failure while adding as few network resources as possible.
