Technical Field

The present disclosure relates to the field of communications, and in particular, to an overhead transmission method, apparatus, device, and computer readable storage medium.

Background

In an Optical Transport Network (OTN), a powerful Network maintenance management function is implemented by overhead, and overhead processing plays an important role in the OTN, including: APS/PCC (automatic Protection Switching/Protection Communication Channel), GCC (General Communication Channel) and some reserved overhead are used to transmit the customized information related to the device or user. With the increasing speed and capacity of OTN devices, for large-capacity devices, resources of an FPGA (Field Programmable Gate Array) are increasingly strained, and overhead processing is relatively independent, and it is a common practice to implement overhead processing in one FPGA alone. If overhead information is transmitted in parallel, logic processing is more complex and occupies more hardware pins.
