Abstract: Presented herein are a combination of techniques that will ensure that the traffic is sent to the proxy right from the first packet without any delay using transient transport, and upgraded to Hybrid Information-Centric Networking (hICN) immediately upon completion of the stack initialization and we have full connectivity. More specifically, a mechanism is provided to dynamically establish hICN connections to transport latency-sensitive traffic, due to a transient User Datagram Protocol (UDP) fallback. This allows a reliable conversion between the push-based IP model, and the pull-based hICN model with no connectivity interruption. This is useful to implement proxy functionalities exposing regular IP applications to hICN to leverage its benefits in terms of performance or seamless mobility.

Abstract: Systems and methods for associating a client computing device with an edge node. The method includes providing, by a cloud server, a resource to the client computing device. Filtering, by the cloud server, one or more edge nodes to identify a subset of edge nodes that meet a predetermined criteria and communicating the subset of edge nodes to the client computing device. The client probes the subset of edge nodes, and based on at least the probing results, the cloud server then selects one of the edge nodes from the subset to provide the resource to the client computing device.

Abstract: In one embodiment, a device that executes an application obtains a delay budget objective for traffic for the application to be sent by a Hybrid Information-Centric Networking source to the device. The device makes a determination as to whether the traffic for the application to be sent by the Hybrid Information-Centric Networking source to the device should use a forward error correction mechanism or a retransmission mechanism, in an attempt to optimize the delay budget objective. The device sends, to the Hybrid Information-Centric Networking source, a Hybrid Information-Centric Networking request for the traffic for the application, wherein the Hybrid Information-Centric Networking request is indicative of the determination. The device receives, from the Hybrid Information-Centric Networking source, one or more packets of the traffic for the application, after sending the Hybrid Information-Centric Networking request.

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: The present disclosure describes systems and methods for migrating communications between a client device and an application hosted by a cloud server. The method includes receiving from an edge server a signal from a client device requesting the establishment of a new communication path between the client device and the cloud server through the edge server. A first connection between client device and the edge server is established, and a second connection between the edge server and cloud server is also established. Once the connections are established, the communication between the client device and the application is migrated from a direct connection between the client device and cloud server to the first and second connections.

Abstract: Content can be delivered by a producer service to one or more consumer services over an information centric network (“ICN”) by storing application frames in a forwarding cache of an ICN node. The consumer services may retrieve applications frames from the ICN node rather than from the producer service directly.

Abstract: The present disclosure describes systems and methods for associating a client device with an edge server. The method includes receiving by each of a plurality of cloud servers a signal from a client device requesting a resource provided by the plurality of cloud servers. Each of the cloud servers then calculates a distance between each cloud server and the client device, and an approximate location of the client device may be determined based on the calculated distance and the known location of the cloud servers. Using the approximate location of the client device, at least one of a plurality of edge servers that are located within a predetermined distance of the client device is identified by the cloud server, and the cloud server or client device may choose one of the identified edge servers through which the client device may be associated to communicate with the cloud server.
