  • Patent number: 10833999
    Abstract: Disclosed herein are a packet management apparatus and method. The packet management apparatus includes: a traffic prediction unit configured to predict the amount of data traffic to be generated based on the number of forwarding information items present in a pending interest table (PIT); and a proactive congestion control unit configured to probabilistically drop request packets (interests) based on the amount of data traffic predicted by the traffic prediction unit. The packet management method includes the steps of: (a) predicting, by a traffic prediction unit, the amount of data traffic to be generated based on the number of forwarding information items present in a pending interest table (PIT); and (b) probabilistically dropping, by a proactive congestion control unit, request packets based on the amount of data traffic predicted by the traffic prediction unit.

  • Patent number: 10063476
    Abstract: There is provided a content centric networking system providing a differentiated service that includes a client device that creates an interest packet, an edge router directly connected to the client device in the content centric networking system, that determines a traffic class for an interest packet on the basis of the information included in an interest packet received from the client device, and marks the determined traffic class information in association with the interest packet; and a differentiated service router, which when receiving the interest packet added with the traffic class information, stores the traffic class information in a pending interest table (PIT) and differentially transmits the data requested by the interest packet in accordance with the traffic class information.

  • Patent number: 9485288
    Abstract: There is provided a peer-to-peer communication method in a content centric network environment. In embodiments, the peer-to-peer communication method in a content centric network (hereinafter referred to as a “CCN”) environment includes, receiving, by a CCN router, a join message including a desired service name of a user node from the user node, transmitting, by the CCN router, the join message to a rendezvous point mapped to the service name and forming a share tree, receiving, by the CCN router, a content request message including a name of content that is provided through the service from the user node, and transmitting, by the CCN router, the content request message through an interface connected to the share tree.

  • Patent number: 6909693
    Abstract: A model is given for performance evaluation of IP computer networks that are dominated by congestion-controlled traffic. The model includes heterogeneous TCP flows, UDP flows, short-lived TCP flows, and TCP flows in a differentiated services network. The performance of large-scale networks is estimated where flows may encounter multiple congested links.
