Problems solved by technology

[0005] When the data flow is transmitted between different nodes on the optical path, light waves of the same wavelength need to be used. However, due to the randomness of the transmission services of each node, the allocation of spectrum resources is also relatively disordered, and a large number of spectrum resources often cannot be used.
For example, among 3 transmission nodes including A, B, and C, there exists a wavelength λ 1 , lambda 2 Two optical paths, among which λ is used between AB 1 Transport data stream 1, use λ between BC 2 Data stream 2 is transmitted. At this time, data stream 3 needs to be transmitted from A to C through B. Although there are spare spectrum resources among A, B, and C, the transmission of data stream 3 cannot be completed.
Therefore, the utilization rate of spectrum resources is low

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...
