Abstract
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.

A G.709-based multi-stage multiplexing routing control method, comprising:
- 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, to implement multi-stage multiplexing configuration and management of an optical transport network through said gateway network element;
- said multi-stage multiplexing capability comprising information of multiplexing hierarchy supported by a port of a link connected to said gateway network element and adaptation capability.
A gateway network element, comprising a multi-stage multiplexing capability configuration module and a configuration and management module, wherein:
- said multi-stage multiplexing capability configuration module is configured to:
- broadcast the multi-stage multiplexing capability of said gateway network element to a routing domain where said gateway network element is located or a path calculation entity through an extended routing protocol;
- said configuration and management module is configured to:
- achieve multi-stage multiplexing configuration and management of an optical transport network through the configured multi-stage multiplexing capability;
- wherein, said multi-stage multiplexing capability comprises information of multiplexing hierarchy supported by a port of a link connected to said gateway network element and adaptation capability.
