Spectrum allocation method and device, and storage medium

Abstract

The invention discloses a spectrum allocation method and device, and a storage medium. The method comprises the following steps: constructing a neural network model; acquiring a first transmission parameter and a first crosstalking value corresponding to an optical fiber path segment in a space-division multiplexing optical network, generating a training sample to train the neural network mode toacquire an optical fiber transmission model; orderly acquiring second transmission data parameters corresponding to multiple candidate path segments, inputting the second transmission data parametersinto the optical fiber transmission model to perform prediction, thereby acquiring a second crosstalking value; selecting a service sending path from candidate paths based on the second crosstalking value, and establishing a fiber core sending path for sending service stream based on the service sensing path. Through the method, device and storage medium disclosed by the invention, a feasible andeffective solution is provided for the resource allocation in consideration of complex crosstalking, the blocking rate can be lower, the spectrum resource utilization rate is higher, the connection establishment time is shorter, and the use feeling of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a frequency spectrum allocation method, device and storage medium. Background technique [0002] With the vigorous development of emerging services and applications such as high-definition video and the Internet of Things, the demand for network bandwidth is also increasing. Optical network is the infrastructure supporting the entire Internet, and space division multiplexing technology is an important technical direction to break through the limit of single-fiber transmission capacity. The space division multiplexing technology mainly includes designing multiple cores in the same fiber cladding or simultaneously transmitting several linear polarization modes in the same core, or a combination of the two to increase the fiber transmission capacity. Space division multiplexing includes multi-core multiplexing and mode multiplexing. At present, multi-core, few-mo...

AI Technical Summary

Problems solved by technology

When multi-core, few-mode or multi-core few-mode fiber is used as the transmission medium in the optical network, the introduction of crosstalk factors makes the resource allocation algorithm of the network layer more complicated

Although the transmission capacity can be improved by using the new type of optical fiber as the transmission medium, it also introduces a non-negligible crosstalk problem, which will have a certain impact on the transmission of services, and in severe cases, it will also cause service congestion and make it impossible to establish a connection
