  • Patent number: 10419349
    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.

  • Patent number: 9948550
    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.

  • Publication number: 20160087876
    Abstract: Disclosed are a method, equipment and system for forwarding packets in an Information Centric Network (ICN). The method includes: content request packets sent by a first route node in a Virtual Private Network (VPN) are received by a first route node in a public network; the content request packets carry the content name of the request content and the private identification for identifying the request content as the private content; the container identification of the first container for storing the request content is obtained; the content request packets are forwarded according to the container identification of the first container so as to forward the content request packets to a second route node in the VPN, and the content response packets carrying the request content are returned according to the content name of the request content.
