  • Patent number: 11095751
    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.

  • Patent number: 11095702
    Abstract: A consumer sends to a producer Interests to request data packets of a data stream that are generated at a production rate. Each data packet includes a name of the data stream, a segment of data, and a current segment number that identifies the data packet in the data stream and that increments as the data packets are generated. The Interests include the name and segment numbers of segments requested by the Interests. The consumer synchronizes the segment numbers with the current segment numbers and a rate for sending the Interests to the production rate. The consumer sends to the producer the Interests at the rate and with the segment numbers as synchronized, in order to minimize a delay time between when the data packets are generated and when the data packets are received at the consumer. The consumer receives from the producer data packets satisfying the Interests.

  • Patent number: 11050724
    Abstract: A producer communicates over a network with a user application in an infrastructure-as-a-service (IaaS) and an IaaS node. The producer encrypts content with first encryption using a first key and second encryption using a second key, to produce twice encrypted content. The producer encrypts the second key with attribute-based encryption and symmetric encryption using an IaaS key, to produce a twice encrypted second key. The producer provides to the user application the twice encrypted content, the twice encrypted second key, and key information configured to remove the first encryption from the twice encrypted content. The producer provides to the IaaS node the IaaS key to enable the IaaS node to remove the symmetric encryption from the twice encrypted second key, such that the user application and the IaaS node are constrained to exchange with each other key-related information and intermediate decryption results in order to recover the content.

  • Patent number: 11038899
    Abstract: Presented herein are methods for dynamic management of names and of named-based requests for media flows in an Information-Centric Network (ICN)-based real-time communication system. The use of different naming schemes on contribution segments and on distribution segments in such architectures results in an effective low latency and scalable communication model based on the notion of active speakers regardless of the underlying mapping between active speakers and participants controlled by the media bridge. Operations are performed both at client side and at media bridge side to dynamically manage binding of names to speakers, while minimizing overhead and complexity of operations involved by a change of active speaker/quality/layout.

  • Patent number: 11025589
    Abstract: A networked electronic device produces a data object comprising content and assigns a location-independent application-level name to the data object. The location-independent application-level name is independent of any network location at which the content is available. The networked electronic device maps the location-independent application-level name to an IP address, generates a DNS resource record specifying the mapping of the location-independent application-level name to the IP address, and provides the DNS resource record to a DNS network node.

  • Publication number: 20210120091
    Abstract: Techniques for providing Hybrid information-centric networking (hICN) via a proxy application is described. A hICN proxy application provides hICN to legacy applications by diverting network traffic of a plurality of network traffic types to the hICN proxy application and storing network traffic information for the network traffic in a connection table. The hICN proxy application also translates the diverted network traffic to a hICN network traffic protocol and selects a forwarding strategy for the translated network traffic in order to send the hICN traffic over various non-hICN network protocol types. The hICN proxy application also transmits the translated traffic to a server proxy application using the selected forwarding strategy.

  • Patent number: 10931559
    Abstract: A network of routers configure resource nodes connected to the network in accordance with a configuration model including configuration objects that imply resources. A router device among the network of router devices receives, from forwarding paths in the network relative to the router device, originated at the resource nodes and that indicate resources supported by the resource nodes. The router device creates mappings of the resources as advertised to the forwarding paths. The router device receives from the network an Intent request to create a configuration object among the configuration objects, and determines whether the configuration object matches a resource in the mappings. If the configuration object matches a resource in the mappings, the router device generates a new Intent request that identifies the resource, specifically, and forwards the new Intent request along the forwarding path mapped to the resource.

  • Patent number: 10924540
    Abstract: In one embodiment, a device in a network receives an interest request for one or more pieces of content data available in the network. The interest request specifies the one or more pieces of content data via one or more bits sets in a content request bitmap of the interest request, each bit of the content request bitmap being associated with a different piece of content data. The device compares the content request bitmap to a content availability bitmap in a forwarding information base (FIB) of the device that is associated with a particular interface of the device and each bit of the content availability bitmap indicates whether a particular piece of content data is available via the particular interface. The device forwards the interest request via the particular interface, based on the comparison between the content request bitmap and the content availability bitmap in the FIB of the device.

  • Patent number: 10911207
    Abstract: This disclosure describes techniques for employing a reusable acknowledgment in communications among network devices. The techniques include generating a reusable negative acknowledgment (NACK) in response to a request for data that are unavailable. The reusable NACK may be sent as a response for at least some additional requests for unavailable data, rather than generating a new NACK for each request. As such, the reusable NACK may help decrease the computational load for a network device. In some cases, the use of a reusable NACK may help lessen the impacts of denial-of-service type attacks across a network.
