Abstract

The invention provides a configuration and binding method and device, equipment, a sending node, a receiving node and a medium. The method comprises the steps of determining a multiplexing structure of an optical layer channel; and configuring channel identification information for a target node according to the multiplexing structure, wherein the channel identification information is used for indicating the target node to bind an optical layer channel.

Description

technical field [0001] The present application relates to optical fiber communication, for example, to a configuration and binding method, device, equipment, sending and receiving nodes and media. Background technique [0002] Optical fiber communication has the characteristics of high bandwidth, long transmission distance, and low loss. It has been deployed on a large scale. The electrical-layer customer signal stream can be multiplexed into optical-layer signals for transmission. A fully standardized Optical Transport Unit-Cn (CompletelyStandardized Optical Transport Unit-Cn, OTUCn) signal can be divided into multiple flexible optical transport network (Flexible Optical Transport Network, FlexO) physical channels, and each FlexO physical channel can be divided into multiple sub-channels , each sub-channel is transmitted through a separate Optical Time Slot Interchanger (OTSi) signal, corresponding to a single physical interface, and the wavelength center of the OTSi signal...

AI Technical Summary

Problems solved by technology

However, the optical media layer multiplexing standard does not involve sub-channels and the correspondence between sub-channels and physical interfaces. The overhead information composition method of the optical media layer is not suitable for the FlexO signal format defined by the OTN interface standard, and cannot distinguish between different OTSi The signals are encapsulated separately, and it cannot provide enough information to support multiplexing and demultiplexing of OTUCn signals

Because the multiplexing of optical layer channels cannot be effectively configured, the binding of optical channels or the creation of optical layer paths cannot be accurately realized, and the multiplexing reliability of optical layer channels is low.
