Title:
DUAL UPLINK METHOD, OPTICAL NETWORK MANAGEMENT DEVICE, AND OPTICAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/091350
Kind Code:
A1
Abstract:
Provided in the present application are a dual uplink method, an optical network management device, and an optical transmission system. An optical transmission device in the optical transmission system is connected to the optical network management device via an in-band management channel and an out-of-band management channel. The method comprises: acquiring a state parameter of the in-band management channel; determining whether the in-band management channel is normal on the basis of the state parameter; if yes, then transmitting management control information via the in-band management channel; and if not, then transmitting management control information via the out-of-band management channel. With the employment of embodiments of the present application, solved is the problem in the prior art in which an out-of-band DCN could not transmit a large volume of real-time monitoring data due to low bandwidth; secondly, eliminated is the problem with connection reliability of a single uplink scheme; and thirdly, subsystems of the optical transmission network are decoupled, and optical network devices can be from different manufacturers.
