1. A computer-executable method for correctly processing interests in an information-centric network (ICN), the method comprising:

  • receiving, by a first node in the ICN, an interest for a piece of content from a second node, wherein the interest specifies a name of the content piece;

    determining, based on forwarding information, whether a forwarding condition is satisfied;

    determining, based on information associated with pending interests stored on the first node, whether an interest aggregation condition is satisfied, wherein the interest aggregation condition is satisfied when a distance from the first node to a destination node is less than a distance from the second node to the destination node and wherein the information associated with pending interests comprises a number of allowed retransmissions and a remaining lifetime of the interest for a piece of content;

    in response to the forwarding condition being satisfied, forwarding the interest;

    in response to the interest aggregation condition being satisfied, aggregating the interest, wherein aggregating the interest comprises not forwarding the interest; and

    in response to neither the forwarding condition nor the interest aggregation condition being satisfied, dropping the interest and sending to the second node a control message indicating that the interest is traversing a loop.
