Data processing method, optical transmission device, and digital processing chip

A digital processing chip, wherein the chip comprises a processor and a memory, the memory and the processor are interconnected by a data line, the memory stores an instruction, and the processor is configured to execute the instruction to perform the following data processing method:

• compressing a to-be-transmitted data stream to obtain a compressed data stream;
• determining a size of a first payload area based on the compressed data stream, wherein the first payload area carries a forward error correction (FEC) code;
• generating a data frame based on the compressed data stream, wherein the data frame comprises an overhead area and a payload area, the payload area comprises the first payload area and a second payload area, and the second payload area carries the compressed data stream;
• performing an FEC processing to generate the FEC code to be stored in the first payload area;
• and
• sending the data frame;
• wherein the obtaining of the size of the first payload area of the compressed data stream comprises:
• obtaining a compression ratio of the compressed data stream, wherein the compression ratio is a ratio of a data volume of the compressed data stream to a data volume of the to-be-transmitted data stream;
• and
• determining the size of the first payload area based on the compression ratio.

An optical transmission device, comprising:

• a processor, a memory, and an optical transceiver, wherein the processor, the memory, and the optical transceiver are interconnected by a data line, and the processor is configured to:
• compress a to-be-transmitted data stream to obtain a compressed data stream;
• determine a size of a first payload area based on the compressed data stream, wherein the first payload area carries a forward error correction (FEC) code;
• generate a data frame based on the compressed data stream, wherein the data frame comprises an overhead area and a payload area, the payload area comprises the first payload area and a second payload area, and the second payload area carries the compressed data stream;
• perform an FEC processing to generate the FEC code to be stored in the first payload area;
• and
• send the data frame to the optical transceiver;
• wherein the optical transceiver sends the data frame;
• wherein the processor is configured to:
• obtain a compression ratio of the compressed data stream, wherein the compression ratio is a ratio of a data volume of the compressed data stream to a data volume of the to-be-transmitted data stream;
• and
• determine the size of the first payload area based on the compression ratio.
