Bit error indication method for service stream and communication apparatus

A communication apparatus, comprising at least one processor and a transceiver, wherein

• the transceiver is configured to receive a first signal stream from a first node by using N slots of a first bonding group, wherein the first signal stream comprises a first check code for determining a quantity of bit errors comprised in the first signal stream, wherein the first bonding group comprises P physical layer (PHY) links, a bandwidth resource of each PHY link is divided into Q slots, a bandwidth resource of the first bonding group is divided into P*Q slots, N is less than or equal to P*Q, and N, P, and Q are all integers greater than or equal to 1;
• the at least one processor is configured to determine a first check value indicating the quantity of bit errors comprised in the first signal stream based on the first check code, determine a second check value based on the first check value and a current check value, and update the current check value by using the second check value, wherein the current check value is a check value stored by the communication apparatus before receiving the first signal stream and the second check value that is determined to be stored in a bit error counter;
• and
• the transceiver is further configured to send a second signal stream to a second node by using M slots of the first bonding group, wherein the second signal stream comprises a second check code, the second check code comprises a target check value, the target check value is determined based on the second check value, the target check value is less than or equal to a preset threshold, and M is an integer greater than or equal to 1.

A non-transitory, storage medium storing information comprising instructions that, when executed by at least one processor, control a network device to perform operations comprising:

• receiving a first signal stream from a first node by using N slots of a first bonding group, wherein the first signal stream comprises a first check code for determining a quantity of bit errors comprised in the first signal stream, the first bonding group comprises P physical layer (PHY) links, a bandwidth resource of each PHY link is divided into Q slots, a bandwidth resource of the first bonding group is divided into P*Q slots, N is less than or equal to P*Q, and N, P, and Q are all integers greater than or equal to 1;
• determining a first check value indicating the quantity of bit errors comprised in the first signal stream based on the first check code, determining a second check value based on the first check value and a current check value, and updating the current check value by using the second check value, wherein the current check value is a check value stored by the network device before receiving the first signal stream;
• and
• sending a second signal stream to a second node by using M slots of the first bonding group, wherein the second signal stream comprises a second check code, the second check code comprises a target check value, the target check value is determined based on the second check value, the target check value is less than or equal to a preset threshold, and M is an integer greater than or equal to 1.
