Traffic monitoring method and apparatus, integrated circuit, and network device

A traffic monitoring apparatus, comprising:

• a processor;
• and
• a transceiver;
• and
• wherein the transceiver is configured to receive a first packet;
• wherein the processor is configured to determine whether the traffic monitoring apparatus comprises a first register, wherein the first register comprises first information and second information, wherein the first information in the first register indicates a depth of a data bucket that carries a measured value of a target performance indicator of a to-be-monitored packet, and wherein the second information in the first register has a value of 0 and indicates a quantity of packets that are in packets received by the traffic monitoring apparatus and that match a value of the first information in the first register;
• and
• wherein the processor is further configured to:
• in response to determining that the traffic monitoring apparatus comprises the first register, update the value of the first information in the first register to a measured value of the target performance indicator of the first packet, and increase the value of the second information in the first register by 1.

An integrated circuit, comprising:

• a control circuit;
• and
• an interface circuit;
• wherein the interface circuit is configured to receive a first packet;
• wherein the control circuit is configured to determine whether the integrated circuit comprises a first register, wherein the first register comprises first information and second information, wherein the first information in the first register indicates a depth of a data bucket that carries a measured value of a target performance indicator of a to-be-monitored packet, and wherein the second information in the first register has a value of 0 and indicates a quantity of packets that are in packets received by the integrated circuit and that match a value of the first information in the first register;
• and
• wherein the control circuit is further configured to:
• in response to determining that the integrated circuit comprises the first register, update the value of the first information in the first register to a measured value of the target performance indicator of the first packet, and increase the value of the second information in the first register by 1.
