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.
