A kind of SDN-based optical fiber network control device and method

Abstract

The invention discloses an SDN-based optical fiber network control device, which is applied to an SDN controller. The SDN controller controls an SDN transponder and an optical fiber network connected thereto. The device includes a user interface module, a monitoring module, and a control module. The user interface module is used to receive the control strategy for the fiber network input by the user and present the fiber network information to the user; the monitoring module is used to monitor the parameters of the fiber network; the control module is used to The parameters of the network control the fiber optic network. Through the scheme disclosed in the present invention, the range of controllable control surfaces of the SDN controller is extended to the optical fiber network, thereby realizing flexible control of the optical fiber network, improving resource utilization, and reducing difficulty and cost of operation and maintenance.

Description

technical field [0001] The present invention relates to the communication field, in particular to an SDN-based optical fiber network control device and method. Background technique [0002] The optical fiber communication system is a widely used optical communication system, and the optical signal is transmitted along the optical fiber to carry a high-speed signal. People expect to give full play to the potential of optical fiber and make one optical fiber carry more information, so fiber multiplexing technology is produced, one of which is optical wavelength division multiplexing. Wavelength Division Multiplexing (WDM) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the sending end through a multiplexer (also known as a multiplexer, Multiplexer). And coupled to the same optical fiber for transmission; at the receiving end, the optical carrier of various wavelengths is separated by a demultiplexer (also known as a...

AI Technical Summary

Problems solved by technology

However, there are still many problems in the current wavelength division multiplexing system. For example, WDM equipment cannot be linked with other data communication equipment, and the physical fiber link level and wavelength link level cannot be protected according to the dynamic attribute parameters of the link. The dynamic attribute parameters of the link do a good job of load balancing for physical fiber links and wavelength links, and cannot perform status monitoring and workload protection for optical modules, etc.
