Abstract
Provided are a congestion control method, device and system. The congestion control method includes: receiving, by a source device, through a first port a local anti-congestion response message sent from a sink device, wherein the local anti-congestion response message is sent after the sink device determines that the length of data cached in a port sending queue for a second port of the sink device corresponding to the first port exceeds a threshold; and suspending, by the source device, sending of a data packet which needs to be sent to the second port through the first port. Hop-by-hop congestion control for the data packets of nodes in a content centric networking (CNN) is timely and accurately realized.
