Abstract: A method and an apparatus for sending a TCP data packet and a system. The method includes: obtaining a first round-trip time of sending a TCP data packet in a network, and determining a second round-trip time; if the first round-trip time is longer than the second round-trip time, using a congestion window determined according to a first algorithm as a first congestion window; otherwise, using a congestion window determined according to a second algorithm as the first congestion window; and sending the TCP data packet by using the first congestion window. In the technical solution disclosed in the present invention, a current congestion window that exists when a first round-trip time is obtained grows to a first congestion window at one go, so that a requirement of a service for a throughput can be better met, and a network bandwidth can be utilized more effectively.

Abstract: Embodiments of the present invention provide a network congestion control method, a device, and a system. The method includes: receiving a first congestion control message, where the first congestion control message carries a 5-tuple of a packet that causes congestion; obtaining a flow identifier of the packet based on the 5-tuple of the packet that causes the congestion; generating a second congestion control message, where the second congestion control message carries the flow identifier corresponding to the 5-tuple; and sending the second congestion control message to a source node of the packet. In the embodiments of the present invention, a network congestion problem of a layer 3 IP network can be resolved.

Abstract: A network congestion control method, a node and a system are disclosed, where the method is applied to a spine-leaf network system. The method includes: a spine node receives network information sent by the at least one leaf node, where the network information includes network topology information of the leaf node and a network performance indicator of the leaf node; networks the at least one leaf node and the spine node based on the network topology information of the at least one leaf node, to obtain a combined network topology; and if the combined network topology is a global network topology of the spine-leaf network system, performs network congestion control on the at least one leaf node based on the network performance indicator of the at least one leaf node.
