  • Patent number: 10819645
    Abstract: The disclosure relates to technology for a 360 degree video stream in a network. A network round trip time (RTT) is measured for a requested FoV of the 360 degree video stream, where the RTT indicates a time interval between sending a FoV interest message and receiving a response message in reply to the requested FoV. The network bandwidth is measured for the requested FoV of the 360 degree video stream, where the measured network bandwidth represents an amount of data the network transmits in the response message. A future FoV of the 360 degree video stream is then determined based on the requested FoV, the measured network bandwidth and the measured network RTT, and a video stream is prefecthced for the future FoV of the 360 degree video stream.

  • Patent number: 10819821
    Abstract: The present technology provides a new content-based centrality metric that may be used for allocating content to caches in a network. The proposed method for measuring centrality and allocating content not only considers the topology of the network, but also the distribution of cache spaces and content among the cache spaces in the network in order to improve how content may be allocated. This approach to content allocation enables improved content retrieval in the form of higher cache hit rates, lower delays and improved network performance.

  • Patent number: 10819685
    Abstract: A network device includes a transmitter and a receiver to establish a secure connection with one or more network nodes as part of a Autonomic Control Plane (ACP) network. The network device also includes a processor coupled to the transmitter and receiver. The processor receives a request from an application to initiate a connection with a destination network node. The processor also receives packets from the application for transmission toward the destination network node. When the packets from the application are unencrypted, the processor end-to-end encrypts the unencrypted packets without notifying the application. The transmitter then transmits the encrypted packets towards the destination network node across the ACP network.

  • Patent number: 10810268
    Abstract: A system and method for improved online transaction processing (OLTP) in a sharded database is provided. Overhead associated with a global transaction manager is reduced and scalability improved by determining whether incoming queries are single-shard transactions or multi-shard transactions. For multi-shard transactions, a distributed transaction ID (DXID) is requested from the GTM, and then forwarded with the query to one or more data notes. For single-shard transactions, the query is sent to a data node without requesting a DXID from the GTM.

  • Patent number: 10805928
    Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.
