摘要

本文提出了一种在透明光网络中单次故障恢复呼叫的新算法。该算法在故障发生后，对光信噪比较高的路由进行路径恢复搜索。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。我们在三种不同场景的恢复过程中实现了较低的故障率。关键词:可生存光网络，透明光网络，路径恢复，物理损伤。

A Novel Restoration Algorithm Based on Optical Signal-to-Noise Ratio for Transparent Optical Networks

In this paper, we propose a novel algorithm to restore calls upon a single failure in transparent optical networks. After a failure, the proposed algorithm performs a path restoration searching for the route which presents the higher optical signal-to-noise ratio. We compared our proposal to three other well known approaches in the literature. We achieved lower failure rates in the restoration process for three different scenarios. Keywords— Survivable Optical Networks, Transparent Optical Networks, Path Restoration, Physical Impairments.
