System and method for implementing an automatic discovery function in a DWDM network
A system and method for implementing an automatic discovery function in a DWDM network are provided, wherein the system includes: an optical supervisory channel (OSC) being a bi-directional physical channel, configured to transmit information through multiplexing/de-multiplexing a wavelength independent of a master optical channel with the master optical channel; a first ASON control unit, being located in a first node, configured to interact with a second ASON control unit in an adjacent second node through the OSC channel so as to obtain the information of the second ASON control unit; and the second ASON control unit, being located in the second node, configured to interact with the first ASON control unit in the adjacent first node through the OSC channel so as to obtain the information of the first ASON control unit. Thereby, using the method and system of the present invention, the automatic discovery function can be implemented through the OSC channel transmission mechanism.
