Abstract: Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.

Abstract: A method includes determining, by a user equipment (UE), to use a first radio access technology, and triggering, by the UE, a first event to disable a second radio access technology while the UE currently uses the second radio access technology. The first event indicates that a base station fails to configure a secondary cell or instructs the base station to delete a configured secondary cell. The secondary cell is a secondary cell of the second radio access technology on the unlicensed spectrum.

Abstract: This application provides a data transmission method. The method includes: calculating a first duration based on at least one to-be-sent data flow and a first time interval, where the first time interval is a preset value, and different data flows in the at least one to-be-sent data flow have different 5-tuples; and sending a first data flow, where the first data flow belongs to the at least one to-be-sent data flow; where a first set of packets of the first data flow are sent in a first time period, a second set of packets of the first data flow are sent in a second time period following a second time interval, a duration of the first time period and a duration of the second time period are equal to the first duration, and the second time interval is greater than or equal to the first time interval.

Abstract: This application discloses a load balancing method and apparatus, and a device, and relates to the field of network technologies. The method includes: after a packet sent by a server is received, determining whether the packet is a first packet of a flowlet, if the packet is the first packet of the flowlet, determining a destination switch based on a destination address of the packet, determining a weight value of at least one equal-cost path associated with the destination switch in a stored equal-cost path weight table, where the equal-cost path weight table stores a correspondence between the at least one equal-cost path and the weight value, and scheduling, based on the weight value of the at least one equal-cost path, the packet onto a corresponding equal-cost path for transmission.

Abstract: A forwarding path selection method and device are disclosed. If a data packet to be sent to a target device is a start packet of a flowlet in which the data packet is located, a sender device selects a low-load path from a plurality of paths to forward the data packet, and sets a forwarding decision of a flow in which the data packet is located to the selected path, where load of each path is load of traffic received by a corresponding intermediate device from the sender device or load of traffic sent by a corresponding intermediate device to the target device, whichever is higher. Flowlet-based load balancing can be implemented only by providing related functions on one type of device.
