Abstract: Embodiments of the present disclosure provide a network congestion control method, where the method includes: sending, by a transmit end device, forward probe packets to a destination device at a preset initialized rate, where some or all of the forward probe packets arrive at the destination device after being rate-limited forwarded by using a reserved bandwidth of an egress port of an intermediate device in a network; receiving return probe packets returned by the destination device, where the return probe packets correspond to the probe packets received by the destination device; and determining a data packet sending rate based on the received return probe packets, and sending a data packet at the data packet sending rate.

Abstract: A data transfer method and a virtual switch, where when receiving a data packet, the virtual switch extracts characteristic information of the data packet, and determines, based on the extracted characteristic information of the data packet, whether an expedited forwarding rule is configured for a data stream to which the data packet belongs. If the expedited forwarding rule is configured for the data stream to which the data packet belongs, the virtual switch bypasses a LINUX bridge to directly send the data packet to a receive end, thereby reducing times of data packet switching between a kernel mode and a user mode, and improving data packet forwarding efficiency.

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.

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: This disclosure provides a scheduling method, a scheduler, a storage medium, and a system, and belongs to the field of communications technologies. The method includes: obtaining an association relationship diagram and data distribution information, where each node in the association relationship diagram indicates one piece of data, and each directed edge is used to indicate an operation request for obtaining, through calculation based on data indicated by a source node, data indicated by a destination node; sequentially positioning, according to a preset node sorting policy, an operation request corresponding to a traversed node to any server in which data indicated by the traversed node is located; and sequentially scheduling at least one operation request indicated by the at least one directed edge to a server to which the at least one operation request is positioned. The method could be used to reduce the cross-node data transmission, and improving calculation efficiency.
