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.

Abstract: Embodiments of the present invention provide a method for routing and forwarding. The method includes: receiving, by a network controller, a routing request message sent by a requesting routing node, where the routing request message carries a content name of requested content; determining, by the network controller according to a network topology diagram and registration information of the requested content, a proper forwarding path; and delivering, by the network controller, routing information to each routing node on the forwarding path. In the embodiments of the present invention, a network controller is introduced, and registration information and a network topology diagram are stored in the network controller, so that the network controller may be used to determine a forwarding path of a content request packet, which reduces blindness of routing and forwarding of the content request packet in an ICN network and improves efficiency of routing and forwarding.
