WDM抗毁网中考虑链路故障相关性的双链路失效保护算法

A Dual-Link Failure Protection Algorithm with Correlated Link Failure Probability for Survivable WDM Networks

  • 摘要: 光纤链路由于共享了相同的物理资源,因此具有一定的故障相关性.这种故障相关性可以用相关链路失效概率(Correlated Link Failure Probability,CLFP)来表示.在CLFP基础上,该文研究了WDM抗毁网中双链路失效问题,提出了一种新的支持用户区分可靠性(Differentiated Reliability,DiR)的共享通路保护算法:SPPDLF-DiR(Shared-Path Protectionfor Dual-Link Failures with DiR).仿真表明,SPPDLF-DiR在满足用户区分可靠性要求的前提下,能有效地提高资源利用率和降低业务阻塞率.
