采用波分复用和波长路由的光网络是未来广域网的潜在候选者。由于这些网络容易出现组件故障并承载大量流量，因此保持高水平的服务可用性是一个重要问题。本文讨论为基于 WDM 的传输网络中的光层提供容错能力。它对文献中可用的恢复方案进行了调查，解释了这些方案的操作，并讨论了它们的性能。
Optical networks employing wavelength-division multiplexing and wavelength routing are potential candidates for future wide area networks. Because these networks are prone to component failures and carry a large volume of traffic, maintaining a high level of service availability is an important issue. This article discusses providing tolerance capability to the optical layer in WDM-based transport networks. It presents a survey on restoration schemes available in the literature, explains the operation of these schemes, and discusses their performance.
