Abstract: Embodiments of this application disclose a traffic monitoring method and apparatus, an integrated circuit, and a network device. When the traffic monitoring apparatus receives a packet, after determining that the traffic monitoring apparatus includes an empty first register, the traffic monitoring apparatus updates a value of first information in the first register to a measured value of a target performance indicator of the packet, and increases a value of second information in the first register by 1. The value of the second information in the first register is 0, the first information in the first register indicates a depth of a data bucket that carries a measured value of the target performance indicator of a to-be-monitored packet, and the second information in the first register indicates a quantity of packets that are in received packets and that match the value of the first information in the first register.

Abstract: A network performance detection apparatus collects, based on identification information of a received data packet, statistics on data packets having the same identification information to obtain packet block information corresponding to the identification information and sends the packet block information to a second device when statistics collection of the packet block information corresponding to the identification information is completed to determine packet block quality information corresponding to the identification information. The identification information includes a flow identifier and a block identifier. The flow identifier includes a source Internet Protocol (IP) address, a source port, a destination IP address, and a destination port of the data packet. The block identifier is a higher N-bit value of an IP identity (IPID) field in the data packet.
