Description: These days, optical networks worldwide have been widely deployed in various network scales,
including long-haul backbone and metropolitan areas, as well as regional broadband access. In order
to assure a certain quality of service and a service-level agreement of the data delivery as requested
by the network service subscribers, network management plays a very important role in the operation
and administration of practical optical networks. Performance management is among the key aspects of
network management that assures the signal quality during signal transmission, switching, and routing.
It provides several important network functions including (1) providing feedback in the adaptive signal
compensators and equalizers (2) control of network elements (3) link setup, control, and optimization
and (4) fault forecasting, detection, diagnosis, and localization, as well as resilience mechanism
activation.
