CONGESTION METHOD, DEVICE AND SYSTEM

摘要

Provided are a congestion control method, device and system. The congestion control method comprises: through a first port, a source end device receiving a local anti-congestion answer message transmitted by a destination end device, wherein the local anti-congestion answer message is transmitted after the destination end device determines that the length of cached data in a port transmission queue of a first port-corresponding second port in the destination end device exceeds a threshold; and the source end device suspending the transmission of data packets which need to be transmitted to the second port through the first port. Hop-by-hop congestion control for the data packets of nodes in a CNN (Content Centric Networking) is timely and accurately realized.
