Method, system and apparatus for distributing node information

摘要

A method for distributing node information, including the following steps: an optical node generates an information bit stream based on its own node information; the optical node distributes the information bit stream it generates and a wavelength sequence corresponding to the node information. According to the embodiments of the present invention, an information bit stream is generated based on the node information of an optical node so as to greatly reduce the volume of data in the node information distributed by an optical node.
