  • Patent number: 9860791
    Abstract: Examples disclosed herein provide systems, methods, and software to control wireless communication policies and rules based on congestion. In one example, a method of operating a Long Term Evolution (LTE) network includes, in a LTE base station, identifying congestion data for one or more communicating wireless communication devices, and identifying that the congestion data meets a congestion criteria. The method further includes, in the LTE base station and responsive to meeting the congestion criteria, setting an explicit congestion notification (ECN) flag for a wireless communication device communication, and transferring the ECN flag for delivery to a LTE gateway. The method further provides, in the LTE gateway, receiving the ECN flag, and identifying a congestion policy for at least one wireless communication device communicating with the LTE base station.

  • Patent number: 9814055
    Abstract: Wireless networking devices scan for available channels and gather data about the channels and the RF environment. Using this information, each wireless networking device determines a cost value for each available channel and a quality value for its overall RF neighborhood. Each wireless networking device select the channel with the best cost value as a candidate channel for use. The wireless networking devices may submit channel requests to the arbiter for approval. If two or more wireless networking devices are requesting the same channel, the arbiter assigns the channel to the wireless networking device with the worst RF neighborhood quality. The arbiter informs the wireless networking devices if their channel requests are approved. If a wireless networking device's channel request is not approved, the wireless networking device will rescan the remaining available channels to select a different candidate channel to be approved.

  • Patent number: 9807013
    Abstract: Techniques and solutions for automatically filtering network broadcast traffic are described. For example, network broadcast traffic can be automatically filtered by turning broadcast filtering on and off (e.g., as a continuous strobe pattern that alternates enabling and disabling of broadcast filtering). For example, a computing device (e.g., via a network interface or management controller of the computing device) can automatically enable network broadcast traffic filtering during a first time period (e.g., a four second time period) and disable network broadcast traffic filtering during a second time period (e.g., a one second time period). A computing device can also automatically enable and disable network broadcast traffic filtering according to an on-off pattern (e.g., based on various criteria, such as network queue size, broadcast traffic volume, etc.).

  • Patent number: 9794172
    Abstract: A virtual edge router network for providing managed services to distributed remote office locations can include routing components that are capable of being autonomously deployed at the network edge, as well as remotely managed, thereby obviating the need for on-site technical support in remote offices of the a small and medium business (SMB) client. Autonomous deployment and remote management is achieved through abstraction of the control and management planes from the data plane. Virtual edge routers may include virtual forwarding units and virtual remote agents instantiated on host devices in each remote office location, as well as a virtual network controller instantiated on a host device in a head-office location. A data plane of the virtual edge router communicatively couples the virtual forwarding units to one another, while a control plane communicatively couples the virtual network controller to each virtual data forwarding unit.

  • Patent number: 9743452
    Abstract: Methods, apparatuses and computer-readable media are described that configure wireless circuitry of a wireless device. The wireless device establishes a connection to a first wireless network using first and second receiving signaling chains. The wireless device obtains a configuration processing delay time for the first wireless network and sends a first channel status report having a rank indicator value of one before starting a tune-away event at a time based on the obtained configuration processing delay time. The wireless device reconfigures at least one of the radio frequency signaling chains to receive signals from a second wireless network during the tune-away event. The wireless device subsequently sends a second channel status report having a rank indicator value greater than one before ending the tune-away event and reconfiguring the at least one of the radio frequency receive signaling chains back to the first wireless network.
