Abstract: This disclosure describes techniques for implementing centralized path computation for routing in hybrid information-centric networking protocols implemented as a virtual network overlay. A method includes receiving an interest packet header from a forwarding router node of a network overlay. The method further includes determining an interest path of the interest packet and one or more destination router nodes of the network overlay. The method further includes computing one or more paths over the network overlay. The method further includes determining an addressing method for the one or more computed paths over the network overlay. The method further includes performing at least one of encoding each computed path in a data packet header, and encoding each computed path as state entries of each router node of the network overlay on each respective path. The method further includes returning the computed path information to the forwarding router node.

Abstract: A network device in a network edge receives content directed to a mobile device attached to the network edge from an upstream network device and forwards the content toward the mobile device. The network device makes a decision whether to cache the content based at least in part on a popularity of the content in a region covered by the network device and a prediction error for an estimated probability that the mobile device will transition from the region to another region. The popularity is directly correlated with a first bias toward caching the content. The prediction error is inversely correlated with a second bias toward caching the content. The decision is implemented: the network device either caches the content or foregoes caching the content, in accordance with the decision.

Abstract: A method is provided in one example embodiment and may include receiving an Internet Protocol (IP) packet at a node; identifying a content semantic for the IP packet; determining whether the IP packet is an IP interest packet or an IP data packet; determining whether content identified in the IP packet is stored at the node based on a determination that the IP packet is an IP interest packet; forwarding the IP packet toward at least one other node based on a determination that the content is not stored at the node; and transmitting an IP data packet containing the content based on a determination that the content is stored at the node.

Abstract: A method is provided in one example embodiment and may include generating an interest message to be transmitted using each face of a plurality of faces associated with a node, wherein the interest message is to be discarded by each of a neighboring node of a plurality of neighboring nodes that receive the interest message; determining, for each face of the plurality of faces associated with the node, a one-hop propagation delay associated with each face of the plurality of faces; and selecting a particular face through which to transmit another interest message based, at least in part, on the one-hop propagation delay of the particular face and a number of pending interests associated with the particular face.

Abstract: An electronic device of a content producer generates a chunk of data, associates a location- independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key. A user device may obtain the public key and use it to verify the chunk of data.

Abstract: In various implementations, a network device receives a packet from a content producer. The packet includes data and further includes a signature generated by the content producer, based on the data, using a private key of the content producer. The network device modifies the packet without affecting the signature and forwards the modified packet toward a user device. The network device also sends the user device a manifest specifying how the packet was modified. The user device receives the packet and manifest, restores the packet's original data based on the manifest, and verifies the original data using the signature and a public key corresponding to the private key of the content producer. In response to verification of the original data, an application on the user device is allowed to use the data.
