Problems solved by technology

In specific implementation, if the OPU2 container holds 2 CBR5G signals, then these 2 CBR5G signals will be dispatched as a particle on the transport network. Since the transport network can only provide monitoring and management for this particle, the 2 CBR5G signals will be used as Two independent access sub-rates cannot be directly scheduled, monitored and managed by the transmission network overhead
[0015] However, if the OPU2 container only accommodates one CBR5G signal, the CBR5G signal needs to be adapted to the OPU2, that is, data encapsulation and rate adaptation of the CBR5G signal need to be performed, and the 10G bearer capacity of the OPU2 can only effectively carry 5G services , so that the container utilization rate of the access node is greatly reduced, and because there is no convergence mechanism, the bandwidth utilization rate of the entire network of the transport network will only be 50%, and the network bandwidth utilization rate is also low

Embodiment Construction

[0123] The signal transmission method and device of the present invention are used to map the CBR5Gbps (hereinafter referred to as CBR5G) signal to the OTN network for transparent transmission, so as to realize the direct scheduling, monitoring and management of the CBR5G granular signal in the OTN, and improve the OTM multiplexing and mapping structure , to improve the flexibility of customer signal multiplexing and mapping.

[0124] refer to figure 2 , which is the main flowchart of the signal transmission method of the present invention.

[0125] First, in step 10, the optical channel (Och) layer is preset to transmit the 5G path optical channel payload unit OPUx and optical channel data unit ODUx frame structure of the CBR5G rate level signal. During specific implementation, the data frame defined by the relevant standard protocol can be used Structure design, such as G.709 protocol, etc.

[0126] Then, in step 11, according to the frame structure of the optical channel...

Abstract

This invention discloses a signal transmission method for optical transmission network, which comprises steps: a. presetting the OPUx and ODUx frame structure in 5G path optical channel for CBR5G signal; b. multiplexing and mapping the CBR5G into optical channel layer to transfer according to said frame structure. Besides, the invention also discloses a corresponding device. Thereby this invention realizes total transmission and monitor in OTN for CBR5G signal.

Description

technical field [0001] The present invention relates to the technical field of optical communication, and more specifically, the present invention relates to a signal transmission method and device applied in an Optical Transport Network (OTN, Optical Transport Network). Background technique [0002] The rapid development of data communication has brought about an information explosion and caused a sharp increase in the demand for transmission network bandwidth. Optical fiber communication has the characteristics of large capacity and high bandwidth, so it has become a better solution to solve the transmission network bandwidth. At present, SONET / SDH technology has been accepted as a mature standard of transmission network. Traditionally, the backbone network used for high-speed transmission is based on SONET / SDH technology. [0003] But the main disadvantage of SONET / SDH networks is that they are optimized for Time Division Multiplexing (TDM, TimeDivision Multiplexing) ser...
