Abstract: Example data processing methods, network devices, and media are disclosed. One example method includes obtaining, by a first network device, N pieces of first round-trip time in a first periodicity. The first round-trip time is time consumed when the first network device and a second network device each transmit a packet once through an Xn/X2 interface. A minimum first round-trip time reference value is determined based on the N pieces of first round-trip time. The minimum first round-trip time reference value is a smallest value of the N pieces of first round-trip time. An inter-site synchronization offset value of the first periodicity is determined based on the minimum first round-trip time reference value. The inter-site synchronization offset value of the first periodicity is an inter-site synchronization offset value that exists when the first network device and the second network device transmit packets through the Xn/X2 interface.

Abstract: This application provides a clock state detection method and apparatus, applied to the field of communications technologies, to detect clock states of M base stations. The method includes: receiving detection results of M base stations, where the detection result of each of the M base stations is used to indicate whether the base station receives a detection sequence sent by each of N neighboring stations of the base station, the N neighboring stations belong to the M base stations, both M and N are integers greater than or equal to 1, and N is less than M; and determining clock states of the M base stations based on the detection results of the M base stations.

Abstract: A method for traffic control are provided, includes: obtaining, by a control node, a delay prediction value of a service packet sent by a source node to a destination node after a current moment; and determining, by the control node, a congestion detection result of current traffic transmission based on a packet delay variation trend and the delay prediction value, and sending the congestion detection result to the source node, and the packet delay variation trend corresponds to a congestion duration change.

Abstract: A variation of a packet gap between packets sent from a source node and a packet gap between packets received by a destination node is determined; then an intensity of the packet gap variation is determined; and finally whether transmission congestion occurs between the source node and the destination node is determined according to the intensity of the packet gap variation. Therefore, accuracy of identifying a cause of a packet loss is improved, thereby avoiding impact of a transmission bit error.

Abstract: In the embodiments of the present invention, an error correction mechanism is established as follows: After traffic is preliminarily controlled, an error is corrected based on a traffic control result, that is, a previously determined cause of packet loss is corrected, and then the traffic is controlled again.
