Abstract: This application discloses a method for controlling traffic in a packet-based network. In the method, after receiving a control packet from a transmit end, an intermediate node between the transmit end and the receive end sends a control packet at the head of a first control queue based on first duration, wherein the first duration is obtained based on a committed burst size (CBS) and a first committed information rate (CIR), and the intermediate node is configured to send a packet of a first transmit end to a first receive end in the packet-based network. After sending the control packet in the control queue, the intermediate node sends a first data packet set at the head of a data queue based on the sent control packet, wherein the first data packet set comprises C data packets, and C is an integer greater than or equal to 1.

Abstract: In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.

Abstract: A data scheduling method is applied to a first top of rack (TOR) switch in a data center network (DCN). The data scheduling method comprises using a load of a path as a basis for data scheduling such that a load change status of the DCN can be dynamically sensed.

Abstract: A load balancing method, device and system, where the method includes: determining, based on load statuses of respective probe channels on n paths between a source end and a destination end, a target path with a lightest load in the n paths, where a probe channel is used to transmit a probe packet that includes a bandwidth probe packet; sending a bandwidth probe packet to the destination end through a probe channel on the target path; receiving the bandwidth probe packet returned by the destination end; and sending, based on the bandwidth probe packet returned by the destination end, a to-be-transmitted data packet to the destination end through a data channel on the target path. Therefore, load balancing among a plurality of paths is implemented.
