Claim 0:
1. A method, comprising:
obtaining a first uplink service flow, wherein the first uplink service flow is based on a fourth uplink service flow that is from a third network device;
obtaining a second uplink service flow, wherein the second uplink service flow is based on a fifth uplink service flow that is from a second network device;
selecting, based on a value of a reference signal number, a first data packet that is from the first uplink service flow or the second uplink service flow, wherein the first data packet comprises a first sequence number that is greater than or equal to the value of the reference signal number;
discarding, based on the value of the reference signal number, a second data packet that is from the first uplink service flow or the second uplink service flow, wherein the second data packet comprises a second sequence number that is less than the value of the reference signal number;

obtaining a third uplink service flow based on the first uplink service flow and the second uplink service flow, wherein the third uplink service flow comprises the first data packet;
sending the third uplink service flow to a next hop in an uplink direction of a first network device;
updating, after sending the third uplink service flow, the value of the reference signal number to be the first sequence number from the first data packet;

receiving the fourth uplink service flow from the third network device; and
sending a sixth uplink service flow to the second network device,
wherein the sixth uplink service flow is based on the fourth uplink service flow, and
wherein the sixth uplink service flow is the fourth uplink service flow or is based on copying the fourth uplink service flow.
