Abstract: This application discloses: collecting statistics about a target parameter of a first data flow, where a target queue of a switching device is used to buffer a data packet in at least one data flow, the first data flow is one of the at least one data flow, and the target parameter is used to reflect an amount of data in the first data flow; when a length of the target queue meets a first length condition, determining, based on at least one of the target parameter and an auxiliary parameter of the first data flow, a marking probability corresponding to the first data flow; and performing congestion marking on a data packet in the first data flow based on the marking probability corresponding to the first data flow.

Abstract: 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.

Abstract: A method for automatically marking a U-turn lane line includes: obtaining information about an intersection entry point, information about an intersection exit point, and information about an obstacle at a to-be-marked intersection; and marking a U-turn lane line with a first depth. The first depth is determined based on a second depth of the obstacle. The first depth of the U-turn lane line is determined based on the second depth of the obstacle, so that a marked U-turn lane line does not collide with the obstacle, to mark a more proper U-turn lane line.
