1. A delay statistical method comprising:
obtaining a first packet and a second packet that belong to a measurement period, wherein the first packet comprises a first in-situ flow information measurement (iFIT) header including first flow detection information, the first flow detection information in the first iFIT header comprising a first delay measurement flag, a first flag indicating a first sequence number of the first packet in the measurement period, and a second flag indicating a total quantity of packets having delay measurement flags in the measurement period, wherein the second packet comprises a second iFIT header including second flow detection information, the second flow detection information in the second iFIT header comprising a second delay measurement flag, a third flag indicating a second sequence number of the second packet in the measurement period, and a fourth flag indicating the total quantity of packets, wherein the first iFIT header comprises a first flow instruction indicator (FII), a first flow instruction header (FIH), and a first flow instruction extension header (FIEH), wherein a first reserved field of the first FIEH carries the first flag and the second flag, wherein the second iFIT header comprises a second FII, a second FIH, and a second FIEH, and wherein a second reserved field of the second FIEH carries the third flag and the fourth flag;
obtaining a first delay parameter of the first packet based on the first flow detection information in the first iFIT header;
obtaining a second delay parameter of the second packet based on the second flow detection information in the second iFIT header; and
sending the first delay parameter and the second delay parameter to a statistical apparatus.
