摘　　要：在现存的宽带通信网中,网络生存性的重要性得到越来越多的重视。针对网络中跨域故障恢复问题,文章提出一种可应用于多域网络故障恢复的新型双重链路权重机制,并对该故障恢复策略进行了理论分析和程序仿真。仿真结果表明,在网络中应用该策略可以在故障发生之后的短时间内,有效地分散业务流量,降低阻塞率,减少资源冲突产生的概率,大大提高了网络的效率和生存性,使其性能得以明显提高。In the existing broadband communication networks,increasingly greater attention is given to the importance of net-work survivability.This paper proposes a novel dual link weight mechanism applicable to the fault recovery of multi-domain networks and conducts theoretical analysis and program simulation of this strategy.The simulation results indicate that the ap-plication of this strategy in networks can effectively disperse the traffic,lower the blocking rate and reduce the probability of resource contention in a short time after the occurrence of a fault,thus greatly increasing the network efficiency and significant-ly improving its survivability and performance.
