    Abstract: In one embodiment, path routing in a node fabric of an information-centric network (ICN) includes transmitting a request from a source application to an upstream node via node faces of nodes in the node fabric along a path encoded in a Path Steering Value (PSV); and receiving at the source application from the upstream node a reply that travels along a return path encoded in the PSV. The PSV is generated by pairwise encoding pairs of node faces successively traversed by the reply and is represented by a deterministically decodable pairing function. Node face identifiers can be deterministically, i.e., uniquely, decoded from the PSV. The deterministically decodable pairing function is selected from a Cantor function, a Hoperoft and Ullman variant of the Cantor function, Hilbert curve algorithm, Morton code, and a bitwise pairing function.

    Abstract: Embodiments include technologies for identifying an equivalence class identifier in a packet received by a node configured to perform information centric networking (ICN) in an ICN network, where the packet includes a name identifying content associated with a producer node in the ICN network. Embodiments also include determining an equivalence class for the packet by determining a name prefix of the name based, at least in part, on the equivalence class identifier. Embodiments further include taking an action affecting a particular packet, the action based, at least in part, on the equivalence class. In specific embodiments, the name includes a plurality of name components, and the equivalence class identifier is a count indicating a number of name components in the name to be grouped together to determine the name prefix. In further embodiments, the number is greater than a particular number of name components in a routable name prefix.

    Abstract: Content is received within a network by a content receiver based upon fetch requests by the content receiver to a content source, where the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates. A network priority is detected at the content receiver that includes an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network. Fetch requests for content are revised in response to detection of the network priority, where the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates compared with the first adaptation logic scheme.

    Abstract: Aspects of the disclosure are directed to systems, network nodes, and methods performed in a network node. A network node can host a TCP/ICN proxy for routing TCP packets through an ICN network. The network node can serve as a forward proxy or a reverse proxy. As a forward proxy, the network node can receive a first packet at the network node, the first packet compliant with a Transmission Control Protocol (TCP) protocol; encapsulate one or more TCP headers from the first packet into a payload field of a second packet, the second packet compliant with an Information Centric Networking (ICN) protocol; and transmit the second packet to a destination through an ICN network. As a reverse proxy, the network node can receive an ICN packet from an ICN network, decapsulate the ICN packet to its TCP components, and transmit the TCP packet through a TCP network.

    Abstract: An example method for congestion control using congestion prefix information in a Named Data Networking (NDN) environment is provided and includes sensing, at a first node, congestion preventing an interest packet from being forwarded over a link to a second node, generating a prefix marker associated with a class of traffic to which the interest packet belongs, generating a negative acknowledgement (NACK) packet that includes the prefix marker, the NACK packet being indicative of congestion for any interest packet in the class of traffic indicated by the prefix marker over any path that includes the link, and transmitting the NACK packet over the NDN environment towards a sender of the interest packet.
