1. A routing method executed by a node in a content centric network (CCN), the method comprising:

  • receiving an interest packet;

    determining whether a content corresponding to the interest packet is advertised based on a forwarding information base (FIB) of the node;

    in response to the content corresponding to the interest packet being advertised, transmitting the interest packet via a face, the face being determined based on the FIB;

    in response to the content corresponding to the interest packet not being advertised, broadcasting the interest packet within a constrained area and sequentially testing routing paths of successively higher address with respect to a hierarchy of names of the content; and

    in response to a reply packet corresponding to the broadcasting not being received, transmitting the interest packet toward a publisher of the content.
