Lightpath restoration in WDM optical networks
2000
IEEE Network
Preserved Fulltext
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 fault tolerance capability to the optical layer in WDM-based transport networks. It presents a survey on restoration schemes available in the literature, explains
