Abstract
A data transmission method and an apparatus are provided. The method includes: receiving first information indicating a preset duration, and the preset duration corresponds to synchronization delay information between a first QoS flow and a second QoS flow; sending a first data packet by using the first QoS flow, and the first data packet is sent by a first network device at a first time; and sending a second data packet based on the first time and the preset duration, by using the second QoS flow. The second data packet is associated with the first data packet. Therefore, synchronization between a synchronization data packet and a reference data packet is implemented.
Claims20
A data transmission method comprising:
- receiving, by a network device, first information, wherein the first information indicates synchronization delay information between a first quality of service (QoS) flow and a second QoS flow;
- sending, by the network device, a first data packet at a first time, wherein the first data packet is transmitted by using the first QoS flow;
- and
- sending, by the network device, a second data packet based on the first time and the synchronization delay information, wherein the second data packet is transmitted by using the second QoS flow, and the second data packet is associated with the first data packet.
A data transmission method comprising:
- obtaining, by a second network device, information, wherein the information indicates an association relationship between a data packet of a first quality of service (QoS) flow and a data packet of a second QoS flow;
- sending, by the second network device, the information to a first network device;
- and
- sending, by the second network device, a first data packet to the first network device, wherein the first data packet corresponds to the information.
A data transmission method comprising:
- obtaining, by a network device, information, wherein the information indicates synchronization delay information between a first quality of service (QoS) flow and a second QoS flow;
- and
- sending, by the network device, the information to another network device.
