Abstract: 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.

Abstract: A network path measurement method. The method includes: obtaining a first aggregate available bandwidth of a path from the first switching node to a second switching node; obtaining a first available bandwidth of a path from a first target port of a third switching node to the first switching node, where the third switching node is a next-stage switching node connected to the first switching node; obtaining, a second available bandwidth of a path from the second switching node to a fourth switching node, where the fourth switching node is a next-stage switching node connected to the second switching node; and determining a second aggregate available bandwidth of a path from the first target port of the third switching node to the fourth switching node, the second aggregate available bandwidth is a smallest available bandwidth among the first aggregate available bandwidth, the first available bandwidth, and the second available bandwidth.

Abstract: A faulty link detection method includes receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value. All the nodes collect statistical data starting from a unified program clock reference value. The quantity of packets lost between an upstream node and a downstream node among all the nodes is acquired according to the statistical data. A faulty link is determined according to the quantity of packets lost between the upstream node and the downstream node.

Abstract: This application provides a method for transmitting path load information and a network node. The method includes: obtaining, by the network node, M pieces of path load information; aggregating, by the network node into one load metric based on the M pieces of path load information, load of all shortest paths that are from the network node to the destination node and that pass through M adjacent nodes corresponding to the M pieces of path load information, where the load metric indicates total load of all the shortest paths from the network node to the destination node; and sending, by the network node, information about the load metric to another adjacent node other than the M adjacent nodes of all adjacent nodes of the network node.
