METHOD, SYSTEM AND APPARATUS FOR BUILDING WAVELENGTH CHANNEL

摘要

A method, a system, and a device for setting up a wavelength connection are disclosed herein. The method includes: obtaining a wavelength path from a source network node to a destination network node and wavelength impairment compensation information of the wavelength path; and setting up the wavelength connection from the source network node to the destination network node according to the wavelength path, and performing impairment compensation for wavelength signals in an interface of each network node on the wavelength path according to the wavelength impairment compensation information during setting up the wavelength connection. The device disclosed herein includes a path calculation server, a network node device, and a control server. The system disclosed herein is a network communication system. The embodiments of the present invention set up an available wavelength connection efficiently, simply and quickly.
