摘　　要：针对ASON中双链路失效问题,基于相关链路失效概率(Correlated Link Failure Probability,CLFP)的方法分析传统共享链路保护的可靠性,并提出一种新的支持用户区分可靠性(Diferentiated Reliability,DiR)的共享链路保护算法:SLPDLF-DiR(Shared-Link Protection for Dual Link Failures with DiR).通过实验仿真,与传统的共享链路保护算法(Shared-Link Protection)进行性能比较,结果表明SLPDLF-DiR算法在满足用户区分可靠性要求的前提下,不仅能有效地提供双链路失效保护,而且能充分地利用网络资源.For the dual-link failures problem of ASON,the paper analyze the Reliability of the shared link protection based on CLFP and Differentiated Reliability（DiR）,and a novel Shared-Link Protection for Dual-Link Failures with DiR（SLPDLF-DiR） algorithm is proposed.The results show that SLPDLF-DiR not only can satisfy the specific requirements of users but also has good survivability for dual link failures.
