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.

Dependent claims

A network congestion control method, comprising:

establishing mapping relationships between 5-tuples of packets and corresponding flow identifiers of the packets;
in response to detecting a network congestion, obtaining a 5-tuple of a packet that causes the network congestion;
obtaining, based on the established mapping relationships and using the 5-tuple of the packet that causes the network congestion, a flow identifier of the packet that causes the network congestion;
generating a congestion control message, wherein the congestion control message carries the 5-tuple of the packet that causes the network congestion and the flow identifier of the packet that causes the network congestion, wherein the 5-tuple of the packet is encapsulated in a payload field of the congestion control message;
and
sending the congestion control message to a source node of the packet.
