Code block transmission method and apparatus, device, system, and chip

A method, wherein the method is applied to a first control unit, and the method comprises:

• obtaining statuses of N lanes between a first Ethernet interface and a second Ethernet interface, wherein the first control unit is connected to the first Ethernet interface, the N lanes are used to transmit a first code block obtained based on service data, and N is an integer greater than 1;
• stopping, based on the statuses indicating that M lanes in the N lanes are faulty, transmitting the first code block to the second Ethernet interface through the M lanes, wherein M is a positive integer less than N;
• and
• transmitting the first code block to the second Ethernet interface through N-M lanes in the N lanes, and transmitting a second code block to the second Ethernet interface through the M lanes, wherein the second code block is different from the first code block.

A method, wherein the method is applied to a second control unit, and the method comprises:

• obtaining statuses of N lanes between a first Ethernet interface and a second Ethernet interface, wherein the second control unit is connected to the second Ethernet interface, the N lanes are used to transmit a first code block obtained based on service data, and N is an integer greater than 1;
• stopping, based on the statuses indicating that M lanes in the N lanes are faulty, receiving the first code block from the first Ethernet interface through the M lanes, wherein M is a positive integer less than N;
• and
• receiving the first code block from the first Ethernet interface through N-M lanes in the N lanes, and receiving a second code block from the first Ethernet interface through the M lanes, wherein the second code block is different from the first code block.

An apparatus, comprising:

• at least one processor;
• and
• a non-transitory memory storing computer-executable instructions,
• wherein the at least one processor is connected to the non-transitory memory, and the computer-executable instructions, when executed by the at least one processor, cause the apparatus to perform:
• obtaining statuses of N lanes between a first Ethernet interface and a second Ethernet interface, wherein the lanes are used to transmit a first code block obtained based on service data, and N is an integer greater than 1;
• stopping, based on the statuses indicating that M lanes in the N lanes are faulty, transmitting the first code block to the second Ethernet interface through the M lanes, wherein M is a positive integer less than N;
• and
• transmitting the first code block to the second Ethernet interface through N-M lanes in the N lanes, and transmitting a second code block to the second Ethernet interface through the M lanes, wherein the second code block is different from the first code block.
