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: 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: Congestion aware load balancing for distributed storage may be provided. First, a read request for data may be received. The data may have redundancy through coding or through copying. Then it may be determined which K of M possible storage nodes to direct the received read request. K and M may be integers and M may be greater than K. In response to determining which K of M possible storage nodes to direct the received read request, the received read request may be copied into K read requests respectively corresponding to the determined K of M possible storage nodes. The copied K read requests may then be transmitted to the determined respective K storage nodes. And, in response to transmitting the copied K read requests, a client may receive data replies from each of the determined respective K storage nodes.

Abstract: In one embodiment, an intermediate node in a communication network receives a client interest with an indication of a client-requested reverse private path. The reverse private path is a label switched path toward a corresponding client with encrypted client information. In response to receiving the client interest, the intermediate node allocates a label for the reverse private path. The allocated label is mapped to a node from which the client interest is received. The intermediate node then forwards the client interest with the allocated label toward a server. In another embodiment, the server receives a client interest including a client-requested reverse private path from a particular intermediate node and determines a server interest. The allocated label for the client interest is inserted into the server interest which is forwarded toward the client via the particular intermediate node using the allocated label for the reverse private path.

Abstract: In one embodiment, a source top-of-rack (ToR) switch may identify multiple destination ToR switches from a group of ToR switches to send data traffic to. The source ToR switch may be connected to the group of ToR switches via a base network. The system may determine whether each destination ToR switch is suitable for receiving data transmission via a point-to-multipoint wireless flyway. The two or more destination ToR switches that are determined to be suitable may be considered flyway candidate ToR switches. The system may establish the point-to-multipoint wireless flyway between the source ToR switch and the flyway candidate ToR switches. The system may then transmit the data traffic from the source ToR switch to each of the flyway candidate ToR switches via the point-to-multipoint wireless flyway.
