Abstract: The present invention relates to a method for managing packets in a network of Information Centric Networking (ICN) nodes (1, 2a, 2b, 2c, 2d, 2e), the method comprising: —at a first node (1), performing steps of: ? Receiving a request (i) for a data packet (C), and if the data packet (C) is stored, responding to the request (i) by forwarding the data packet (C); otherwise ? sending to at least one neighboring node (2a, 2b) of the network a request (i?) for meta-data packets (@), a meta-data packet (@) indicating availability of said data packet (C) at a target node; ? receiving in response at least one meta-data packet (@), so as to identify at least one target node (2c, 2e) wherein said data packet (C) is available; ? forwarding the request (i) for said data packet (C) toward one selected target node (2c); —at a second node (2a, 2b, 2c, 2d, 2e), performing steps of: ? Receiving a request (i?) for meta-data packets (@), and if the data packet (C) is stored, responding to the request (i?) by forwarding a meta-

Abstract: The present invention relates to an ICN router (1), comprising a first cache layer (L1) and a second cache layer (L2), the first cache layer (L1) comprising a first content memory (11) and the second cache layer (L2) comprising a second content memory (21), the second content memory (21) having a higher capacity but a slower access speed than the first content memory (11), the router (1) being configured so that the first cache layer (L1) is adapted to fetch data from second cache layer (L2) when the router (1) is requested to output said data, characterized in that the first content memory (11) presents a first block size and the second content memory (21) presents a second block size, the second block size being higher that the first block size, the first content memory (11) comprising a swap area (110) through which the first content memory (11) is connected to the second content memory (21), the swap area (110) being adapted for individually serving blocks at the first block size as parts of blocks at the

Abstract: A method for managing packets over interfaces of a Content Centric Networking node, the method comprising the following steps receiving over an interface of the node at least a request for a data packet; if the data packet is stored by the node, forwarding the data packet over the interface of the received request; otherwise performing an exploration step, by selecting randomly at least an interface towards a neighboring node; forwarding the request over the selected interface; receiving in response over the randomly selected interface, the data packet with associated minimum time delivery value estimated by the neighboring node; identifying an interface providing the minimum data packet delivery time value based on exploration step results.
