Abstract
The present disclosure relates to the field of network communication and particularly discloses a method for monitoring performance of a wavelength path. The method includes: receiving, by a second node, a path request message of a wavelength path from an upstream neighboring node, where the path request message includes at least a path identifier of the wavelength path and second wavelength identifier information; obtaining, by the second node, a wavelength identifier according to the second wavelength identifier information, and recording a mapping relationship between the wavelength path and the wavelength identifier; and determining, by the second node according to the wavelength identifier, a low frequency signal modulated at a working wavelength of the wavelength path, and obtaining performance of the wavelength path by monitoring the low frequency signal. A system for monitoring performance of a wavelength path and a node device are also disclosed in embodiments of the present disclosure.
