摘要

本文提出了一种新的全光网络双链路故障恢复算法。我们的建议旨在恢复所有因每次故障而中断的光路。该算法进行路径恢复，寻找光信噪比(OSNR)较高的路径。我们将我们的建议与文献中其他三种众所周知的方法进行了比较。我们观察到，考虑到几种物理层损伤，我们的建议在三种不同的研究场景中获得了较低的恢复过程故障率。

A novel double-link failure restoration algorithm based on optical signal-to-noise ratio for all-optical networks

In this paper, we propose a novel algorithm to restore calls upon double-link failures in all-optical networks. Our proposal aims to restore all the lightpaths disrupted by each failure. The algorithm performs a path restoration looking for the route that presents the higher optical signal-to-noise ratio (OSNR). We compared our proposal to three other well known approaches in the literature. We observed that our proposal obtained lower failure rates in the restoration process for three different studied scenarios considering several physical layer impairments.
