Embodiments of this application disclose path traffic allocation methods and network devices. One of the disclosed path traffic allocation methods includes sending, by an ingress node, a measurement packet to an egress node on each of at least two paths, where the at least two paths are paths between the ingress node and the egress node, and the measurement packet on each path indicates path information of each path. The disclosed method further includes receiving, by the ingress node, a response packet from the egress node, where the response packet indicates traffic adjustment information of each path, and determining, by the ingress node, to-be-sent traffic on each path based on the traffic adjustment information of each path.

Path traffic allocation method, network device, and network system

A data transmission method includes detecting a delay between a source end and a sink end; determining a to-be-used second path when a first path currently used to transmit a packet is determined to be a congested path; determining a delay difference between the first path and the second path based on a delay of the first path and a delay of the second path; and sending one or more to-be-sent packets to the sink end through the second path based on the delay difference.
