A content-centric network node method, a content-centric network node and a computer program product are disclosed. The method comprises: receiving an interest packet over a link from a requesting network node requesting content be provided, the interest packet having a received charge value associated therewith; determining whether the content is available to the network node and, if not, identifying available onward links to other network nodes; splitting the received charge value between duplicated interest packets, each having a transmitted charge value; and transmitting one of the duplicated interest packets over each available onward link. In this way, interest packets may be split and propagated by the network node to be transmitted onto multiple network nodes, but the propagation of those interest packets may be controlled and limited based on the charge associated with those interest packets. Controlling how the charge is allocated between the interest packets and how that charge is affected by propagation through the network provides for a flexible, controllable and efficient arrangement for accessing content in highly reconfigurable, dynamic networks. |
