  • Apparatus for forwarding interest in parallel using multipath in content-centric networking and method thereof
    Patent number: 10666552
    Abstract: The present invention relates to a technology of forwarding interest parallel by adjusting a ratio of an interest packet requiring content depending upon a network state when a mobile device having a variety of interfaces is connected to various networks in a content-centric networking environment, thereby increasing a data transfer rate. An apparatus for controlling multipath interest forwarding according to an aspect of the present invention includes a weighted forwarding ratio administrator configured to generate an interest packet; a weighted forwarding ratio storage configured to record and maintain weighted forwarding ratios reflecting a transmission capacity of an interest packet per face; and a forwarding engine configured to control the generated interest packet to be transmitted via each of the faces based on the weighted forwarding ratios.
