Abstract

Embodiments of the present invention relate to the field of optical communication technologies, and provide a method, device and system for notifying wavelength service information, which may enable each site on a manually and statically provisioned wavelength path to automatically obtain wavelength service information of a transmitted wavelength service, thereby saving a labor cost and achieving a low error rate. The method for notifying wavelength service information includes: obtaining and storing, by a site, wavelength service information of an existing service at an optical cross source after connecting the optical cross source and an optical cross sink according to optical cross-connection information of the existing service, then transferring the wavelength service information from the optical cross source to the optical cross sink according to the optical cross-connection information, and inserting, at the optical cross sink, the wavelength service information into a link management protocol message and sending the link management protocol message to a receiving site, so that the receiving site stores the wavelength service information. The embodiments of the present invention are used for notification of the wavelength service information.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a wavelength service information notification method, equipment and system. Background technique [0002] In the optical communication system, when the existing service is transmitted in the network, the station will modulate the electrical signal of the existing service into an optical signal at a certain signal rate and modulation pattern, and carry it on the optical wavelength for transmission, and transmit it through DWDM ( Dense Wavelength Division Multiplexing (Dense Wavelength Division Multiplexing) technology realizes the multiplexing transmission of multiple services, that is, multiple optical signals with different frequencies, in one optical fiber. When the wavelength service information of multiple existing services is the optical wavelength, When the signal rate and modulation pattern are different, if the optical wavelength interval of the exis...
