G.709 BASED MULTI-STAGES MULTIPLEXING ROUTING CONTROL METHOD AND GATEWAY NETWORK ELEMENT

摘要

A G.709 based multi-stage multiplexing routing control method is provided in the present invention, which includes that: the multi-stage multiplexing capability of the gateway network element is carried in a link state advertisement data packet, and the multi-stage multiplexing capability of the gateway network element is advertised to a routing domain in which the gateway network element is located or a path computation entity through a routing protocol. A gateway network element is also provided in the present invention, the gateway network element is configured to: carry the multi-stage multiplexing capability of the gateway network element in the link state advertisement data packet, and advertise the multi-stage multiplexing capability of the gateway network element to the routing domain in which the gateway network element is located or the path computation entity through the routing protocol. With the above G.709 based multi-stage multiplexing routing control method and gateway network element, advertising the multi-stage multiplexing capability of the gateway network element to other network elements is implemented, thereby solving the problem of interconnection between new devices and old devices.
