  • Patent number: 10333894
    Abstract: System and method for supporting flexible forwarding domain boundaries in a high performance computing environment. In accordance with an embodiment, flexible forwarding domain boundaries can be supported by dividing/partitioning a physical switch into two or more logical switches, where each switch is logically in a different domain, and allowing a fabric to be decomposed into independent subnets with one two or more physical end ports at the physical switch. By doing so, the same hierarchical forwarding structure and management structure between subnets can be provided as when complete physical switches are used as building blocks.

  • Patent number: 10320519
    Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.

  • Patent number: 10313494
    Abstract: Methods and systems for transmitting data packets from a host to a destination via a virtual private network (VPN) connection at a VPN gateway. VPN gateway receives encapsulated packets via the VPN connection. The encapsulated packets encapsulate the data packets originated from the host. VPN gateway decapsulates the encapsulated packets to retrieve the data packets. VPN gateway determines whether the data packets originated from an IoT device based on IP address of the host. When the host is the IoT device, VPN gateway performs deep packet inspection (DPI) on the data packets. VPN gateway determines whether the data packets are allowed to be transmitted to the destination. When the data packets are allowed to be transmitted to the destination, VPN gateway transmits the data packets to the destination.

  • Patent number: 10313416
    Abstract: As may be implemented in a manner consistent with one or more embodiment, aspects of the disclosure are directed to latency control with signals, such as audio signals. For instance, a quality characteristic of an audio signal having time-sequenced frames exhibiting a signal quality can assessed, and an output indicative of the signal quality is provided based on the assessment. An amount of latency in the audio signal is dynamically adjusted based on the output, and the latency can be used in processing the time-sequenced frames, such as to use future frames in assessing or correcting a current frame during a time period facilitated via the latency.

  • Patent number: 10292072
    Abstract: A system with distributed proxy for reducing traffic in a wireless network satisfies data requests made by a mobile application. The system includes a mobile device having a local proxy for intercepting a data request made by the mobile application. The local proxy simulates application server responses for the mobile application on the mobile device for data requests where responses are available in the local cache. A proxy server is coupled to the mobile device and an application server to which the data request is made. The proxy server is able to communicate with the local proxy. The local proxy forwards the data request to the proxy server for transmission to the application server for a response to the data request. The proxy server queries the application server for any changes to the data request that the mobile application has previously made and notifies the local proxy of such changes.

  • Patent number: 10285216
    Abstract: Various embodiments provide dynamic reconfiguration of a connectivity configuration associated with a wireless networking device. The wireless networking device maintains multiple wireless connections with multiple user devices using a combination of beam-formed wireless signals and omnidirectional wireless signals. The wireless network device generates a list of connected or associated user devices that are capable of beam-formed wireless communications, and obtains metrics for each respective user device. The wireless networking device prioritizes the list based upon the respective metrics, and determines whether a current connectivity configuration differs from the prioritization. Responsive to determining a difference, the wireless networking device can dynamically reconfigure the connectivity configuration by modifying a connection type associated with at least one user device.
