Embodiment 1

[0045] Such as figure 1 As shown, in this embodiment, an overhead transmission method includes:

[0046] S10. Extract overhead data and cache it as an overhead frame, where the overhead frame includes: channel number, line number, and overhead data;

[0047] S20. Encapsulate the overhead frame into a custom overhead data frame;

[0048] S30. Perform serial transmission of overhead data according to the type of the custom overhead data frame.

[0049] In this embodiment, the cross-FPGA insertion and extraction of the overhead is realized by adding the channel number, line number, etc. before the overhead and caching them sequentially, and packaging them into a custom package for serial transmission of the OTN overhead. The structure is simple, High portability, greatly saving OTN device pins.

[0050] In this embodiment, the overhead data is extracted from the overhead interface, written into the cache according to the order of the channel number, line number, and overhead d...

Embodiment 2

[0066] Such as Figure 7 As shown, in this embodiment, an overhead transmission device includes:

[0067] An extraction module 10, configured to extract overhead data and cache it as an overhead frame, where the overhead frame includes: channel number, row number, and overhead data;

[0068] An encapsulation module 20, configured to encapsulate the overhead frame into a custom overhead data frame;

[0069] The transmission module 30 is configured to perform serial transmission of overhead data according to the type of the custom overhead data frame.

[0070] In this embodiment, the cross-FPGA insertion and extraction of the overhead is realized by adding the channel number, line number, etc. before the overhead and caching them sequentially, and packaging them into a custom package for serial transmission of the OTN overhead. The structure is simple, High portability, greatly saving OTN device pins.

[0071] In this embodiment, the overhead data is extracted from the overhe...

Abstract

The invention discloses an overhead transmission method, apparatus and device, and a computer readable storage medium, and belongs to the technical field of communications, the method comprising: extracting overhead data, and caching the overhead data as an overhead frame, the overhead frame comprising a channel number, a line number and overhead data; packaging the overhead frame into a custom overhead data frame; and performing serial transmission of overhead data according to the type of the custom overhead data frame. By adding identifiers such as channel numbers and row numbers before expenditure, caching in sequence and packaging into a custom packet for serial transmission of OTN expenditure, cross-FPGA insertion and extraction of expenditure are realized, the structure is simple, the portability is high, and OTN device pins are greatly saved.

Description

technical field [0001] This article relates to the field of communications, and in particular to an overhead transmission method, device, equipment, and computer-readable storage medium. Background technique [0002] In Optical Transport Network (OTN, Optical Transport Network), powerful network maintenance and management functions are realized through overhead, and overhead processing plays an important role in OTN, including: APS / PCC (Automatic Protection Switching / Protection Communication Channel, automatic protection Switching / protection communication channel), GCC (General Communication Channel, general communication channel) and some reserved overhead are used to transmit device or user-related custom information. As the speed and capacity of OTN equipment continue to increase, for large-capacity equipment, FPGA (Field Programmable Gate Array, Field Programmable Gate Array) resources are increasingly tight, and the processing of overhead is relatively independent. Pro...
