A method, apparatus, device and system for spectrum sorting

Abstract

The present application provides a method, apparatus, device and system for spectrum arrangement, belonging to the technical field of communications. The method includes: the sending end obtains the target data stream, uses the frequency band to be adjusted on one line to send the target data stream, and then adjusts the occupied frequency band of the target data stream on the other line from the band adjustment frequency band to the target frequency band, and then adjusts the target data stream to the target frequency band. The data stream switches to this other line, using the desired frequency band for transmission. Through the present application, the effective arrangement of the spectrum can be realized, thereby improving the utilization rate of spectrum resources.

Description

technical field

[0001] The present disclosure relates to the field of optical transmission, and in particular, to a method, apparatus, device and system for spectrum sorting. Background technique

[0002] With the continuous development of network communication technology, optical transmission has become an important data transmission method, and data transmission can be carried out in the form of optical signals between the sender and the receiver of data. Optical transmission mainly uses wavelength division multiplexing technology, which can transmit multiple data streams through light waves of different wavelengths in the same fiber.

[0003] At present, the elastic optical network technology is introduced in the field of optical transmission, that is, the spectrum of the optical fiber is expanded from the traditional fixed spectrum grid to the elastic spectrum grid with smaller granularity, that is, the frequency band bandwidth occupied by each elastic spectrum grid is s...

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] As used in this application, the terms "component," "module," "system," etc. are intended to refer to a computer-related entity, which may be hardware, firmware, a combination of hardware and software, software, or running software. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread in execution, a program, and / or a computer. As an example, both an application running on a computing device and the computing device may be components. One or more components can exist in a process and / or thread of execution, and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute fr...
