  • Patent number: 10205604
    Abstract: A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations.

  • Patent number: 10123352
    Abstract: When contending for access to a radio channel (for example CSMA/CA in Wi-Fi), an apparatus selects a first clear channel assessment (CCA) threshold that is higher than a minimum; determines to temporarily use a second CCA threshold that is lower than the first CCA threshold; and based on this determination it selects the second CCA threshold for a specified time period. In one embodiment this determination is based on the apparatus' use of a spectrum relative to a threshold usage level which may be calculated as a number of successful transmissions by the apparatus on the spectrum over a predefined time period; and/or as a deferring time experienced by the apparatus with respect to the spectrum over a predefined time period. In an embodiment the specified time period comprises a backoff time, and the determination to temporarily use the second CCA threshold is triggered by a periodic timer.

  • Patent number: 10084691
    Abstract: Upon detecting a failure of a switch link in a set of multiple redundant switch links that directly connect two nodes in the switch fabric network, the system performs a failover operation that remaps network traffic associated with the failed switch link to an alternative switch link in the set of multiple redundant switch links. Each node in the switch fabric network maintains a mapping table that translates from logical ports and associated logical virtual lanes to physical ports and associated virtual lanes. The system also provisions switch links with private virtual lanes comprising resources to facilitate failover operations. While remapping the network traffic, the system changes the mapping table so that network traffic, which is presently directed to a physical port and associated virtual lane for the failed switch link, is remapped to an alternative physical port and an associated private virtual lane, for the alternative switch link.

  • Patent number: 10082558
    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

  • Patent number: 10075373
    Abstract: A process capable of facilitating network communication using forwarders or vforwarders interconnected via an overlay network is disclosed. The process, in one aspect, is able to receive a packet stream or network traffic from a customer premise equipment (“CPE”) using a point-to-point (“PTP”) connection via the overlay network. After identifying a service component able to provide a network function (“NF”) in accordance with the packet stream, at least a portion of the packet stream is forwarded to the service component via a second PTP connection through the overlay network according to a set of predefined requirements. Upon receipt of a processed packet stream in response to the packet stream from the service component, the processed packet stream is forwarded to another forwarder via a hop-to-hop (“HTH”) link through the overlay network in accordance with the processed packet stream.
