论文摘要
在本文中，我们提出了一种快速恢复策略，用于弹性光学网络中的双连接故障。弹性光网络是满足下一代更高带宽需求的有前途的解决方案。高速网络的生存能力非常重要。随着网络大小的增加，双链路故障和节点故障的概率也会增加。在这里，我们提出了一个平行的交叉连接备份恢复策略，用于网络中的双链路故障。提出的策略与现有的共享路径保护（SPP）和专用路径保护（DPP）方法相比，提出的较低的带宽阻断概率（BBP），快速连接恢复和带宽配置率。模拟在ARPANET和COST239拓扑网络上进行。
In this paper, we proposed a fast recovery strategy for a dual link failure in elastic optical network. The elastic optical network is a promising solution to meet the next generation higher bandwidth demand. The survivability of high speed network is very crucial. As the network size increases the probability of the dual link failure and node failure also increases. Here, we proposed a parallel cross connection backup recovery strategy for dual link failure in the network. Proposed strategy shows lower bandwidth blocking probability (BBP), fast connection recovery, and bandwidth provisioning ratio when compared with the existing shared path protection (SPP) and dedicated path protection (DPP) approaches. Simulation is performed on ARPANET and COST239 topology networks.
