<p>A G.709 based multi-stage multiplexing routing control method and a gateway network element. The method comprises: a gateway network element broadcasting multi-stage multiplexing capability of the gateway network element to a routing domain where the gateway network element is located or a path calculation entity through an extended routing protocol, so as to implement multi-stage multiplexing configuration and management of an optical transport network through the gateway network element; the multi-stage multiplexing capability comprises information of multiplexing hierarchy supported by a port of a link connected to the gateway network element and adaptation ability.</p> |
