  • Patent number: 9877325
    Abstract: A system and method for joint scheduling in a dual-carrier fixed wireless backhaul network is disclosed, wherein the primary carrier is a licensed band, and the secondary carrier is a lower cost shared band or an unlicensed band. The network comprises a plurality of Hub modules, each serving a cluster of one or more Remote backhaul modules (RBMs). A special frame structure and a control channel on the primary carrier carries control signalling messages for RBMs assigned to either the primary or secondary carrier. RBMs with a performance metric, such a spectral efficiency, above a threshold are assigned to the primary carrier. Other RBMs are assigned the secondary carrier, and a channel assignment is then performed. A transmission mode is determined based on instantaneous channel conditions, to optimize overall system performance across a network neighborhood and meet RBM quality of service requirements. A centralized server/processing unit co-ordinates dual carrier joint scheduling functions.

  • Patent number: 9854533
    Abstract: System and method for improving channel efficiency in a wireless link between an access-point transceiver and a first transceiver. The first transceiver may have a first data throughput rate that is lower than the maximum possible data throughput rate of the wireless link. The first transceiver may include a first receive buffer. An indication of the first data throughput rate and a size of the first receive buffer may be received and stored by the access-point transceiver. A first size of a first data packet for transmission to the first transceiver may be determined by the access-point transceiver based on one or more of the first data throughput rate and/or the size of the first receive buffer. The first data packet of the first size may be transmitted to the first transceiver by the access-point transceiver at a data rate that is higher than the first data throughput rate.

  • Patent number: 9826071
    Abstract: A method for generating configuration data for configuring a hardware switch is described. The method receives a description of functionality for the hardware switch. Based on the description, the method generates sets of match and action entries to configure the hardware switch to process packets. The method then determines, for each packet header field in a parse graph that specifies instructions for a parser of the switch to extract packet header fields from packets, whether the packet header field is used or modified by at least one match or action entry. The method generates for the parser of the hardware switch configuration data that instructs the parser to extract (i) packet header fields used or modified by at least one match or action entry to a first set of registers and (ii) packet header fields not used by any match or action entries to a second set of registers.

  • Patent number: 9792642
    Abstract: It is an object of the present invention to enhance convenience and service qualities in an information distribution system. In a server serving as an information distribution apparatus and an information communication terminal, contents are managed by using content identifiers (content IDs) managed as IDs conforming to a rule of uniformity. Particularly, in the information communication terminal, a content ripped from a recording medium such as a CD and stored in storage means such as an HDD is also managed by using a content identifier acquired from the information distribution apparatus. In this way, contents stored in the storage means can be managed by using content IDs each managed as an ID common to the information communication terminal and the information distribution apparatus.

  • Patent number: 9787573
    Abstract: Techniques are described for providing fast convergence in the event of a link failure in an all-active multi-homed Ethernet virtual private network. A provide edge (PE) network device may pre-configure an interface next hop and secondary next hops. The secondary next hops may be logical links to other PE network devices in the same Ethernet segment. In the event of a link failure in the interface next hop between the PE network device and a customer edge (CE) network device, the PE network device may be configured to forward data traffic to the CE network device using the secondary next hops. In the event of a link failure between the PE network device and a core network, the PE network device may be configured to send an out-of-service message to the CE network device that instructs the CE network device to stop sending traffic to the PE network device.

  • Patent number: 9787361
    Abstract: Embodiments of the invention provide multiple cyclic prefix lengths for either both the data-payload and frame control header or only the data payload. Frame control header (FCH) and data symbols have an associated cyclic prefix. A table is transmitted in the FCH symbols, which includes a cyclic prefix field to identify the cyclic prefix length used in the data payload. A receiver may know the cyclic prefix length used in the FCH symbols in one embodiment. In other embodiments, the receiver does not know the FCH cyclic prefix length and, therefore, attempts to decode the FCH symbols using different possible cyclic prefix lengths until the FCH symbols are successfully decoded.
