  • Patent number: 10045237
    Abstract: Systems and methods which provide white space channel identification and/or selection using high probability area determinations for a device and availability probability calculations for channels based on a probability model are described. A white space device (WSD) may utilize spectrum scanner sensing results to determine one or more course high probability area (HPA) for the WSD. The sensing results may further be analyzed to derive probability information regarding the WSD being located at the HPAs, to thereby refine the HPAs. Thereafter, the information regarding probabilities of the WSD being located at the HPAs may be utilized with information from a white space location database to determine an availability probability of one or more white space channels. One or more such white space channels may be identified and/or selected for use by the WSD.

  • Patent number: 10007630
    Abstract: A method for transmitting data packets from a first device through a switch to a second device is described. The method is performed at an intercepting device intermediate the first device and the switch device. The method comprises receiving a first data packet from the first device, determining that the first data packet is to be transmitted to the second device and determining whether the first data packet is of a first type that can not be transmitted from the intercepting device to the second device through the switch. If the first data packet is of the first type, the first data packet is encapsulated within a second data packet and transmitting the second data packet through the switch to the second device. If the first data packet is not of the first type, the method comprises transmitting the first data packet through the switch to the second device.

  • Patent number: 9998355
    Abstract: It is possible to improve backhaul resource utilization efficiency during dynamic point selection (DPS) transmissions by unicasting different portions of a traffic flow to different access points participating in the DPS transmission. Specifically, a traffic flow may be encoded to obtain forward error correction (FEC) packets, and different subsets of the FEC packets may be unicast to different access points participating in the DPS transmission. The subsets of FEC packets may have partial (or no) redundancy such that the amount of duplicative data communicated over the backhaul network is reduced when compared to multicasting the entire traffic flow to each access point participating in the DPS transmission. There may be different degrees of redundancy between subsets of FEC packets to achieve different traffic engineering (TE) objectives.

  • Patent number: 9992153
    Abstract: Exemplary methods, apparatuses, and systems include a first network edge device configuring a physical network interface to be included within a link aggregation group (LAG). The physical network interface of a second network edge device is also included within the LAG. The first network edge device receives, via the LAG, a first address resolution packet including a source and a destination. The first network edge device determines that the destination of the address resolution packet is a networking address assigned to a logical interface that is unique to the second network edge device. In response, first network edge device transmits the address resolution packet from a synchronization network interface to a synchronization network interface of the second network edge device. The synchronization network interface of each network edge device is excluded from sharing a LAG with network edge device ports of the other network edge device.

  • Patent number: 9923836
    Abstract: Systems and methods are described for configuring a delay based scheduler for an access node. A plurality of packets may be received at an access node, where at least a first packet is associated with an application running on a wireless device in communication with the access node. The plurality of packets may be inspected to determine that one or more of the packets associated with the application are marked, where the mark indicates network congestion. A remaining time for the first packet may be calculated based on a packet delay budget associated with the running application and the determination that one or more of the packets associated with the application are marked. The first packet may then be scheduled for transmission to the wireless device, using a delay based scheduler, based on the calculated remaining time.
