Abstract: Embodiments of the invention disclose a data transmission method, a device, and a computer storage medium to perform data transmission. A congestion status of a transmission port is obtained by a first device. The transmission port is a communications port used by the first device when a second device transmits data to the first device. The congestion status is used to indicate whether data congestion occurs on the transmission port. Indication information is sent to the second device when a mode switching condition is met. The indication information is used to instruct the second device to switch a transmission mode used when the second device transmits the data, so that the second device transmits the data to the first device in a switched transmission mode, and the mode switching condition is associated with the congestion status of the transmission port.

Abstract: The present disclosure relates to congestion flow identification methods. One example method includes obtaining, by a network device, a queue length of a non-congestion flow queue, where the non-congestion flow queue includes a data packet or description information of the data packet, determining, by the network device, a target output port of a target data packet when the length of the non-congestion flow queue is greater than or equal to a first threshold, where the target data packet is a data packet waiting to enter the non-congestion flow queue or a next data packet waiting to be output from the non-congestion flow queue, and when utilization of the target output port is greater than or equal to a second threshold, determining, by the network device, that a flow corresponding to the target data packet is a congestion flow.

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.
