  • Patent number: 8345553
    Abstract: Apparatus and methods for reducing latency in coordinated networks. The apparatus and methods relate to a protocol that may be referred to as the Persistent Reservation Request (“p-RR”), which may be viewed as a type of RR (reservation request). p-RR's may reduce latency, on average, to one MAP cycle or less. A p-RR may be used to facilitate Ethernet audiovisual bridging. Apparatus and methods of the invention may be used in connection with coaxial cable based networks that serve as a backbone for a managed network, which may interface with a package switched network.

  • Publication number: 20120300861
    Abstract: Forward error correction (FEC) m-bit symbol modulation. Any desired FEC, error correction code (ECC), and/or combination thereof generates coded bits for combination with either uncoded bits, separately generated coded bits, and/or combination thereof to generate a number of symbols that undergo mapping to a constellation whose respective constellation points have a mapping characterized by a maximum minimum intra-Euclidean distance between the respective constellation points thereby generating a sequence of discrete-valued modulation symbols. The sequence of discrete-valued modulation symbols may then undergo modulation of any of a number of different operations (e.g., digital to analog conversion [e.g., digital to analog converter (DAC)], scaling, frequency shifting, filtering, etc.) to generate a continuous time signal for transmission via a communication channel. Such a device operative to perform including such functionality, circuitry, capability, etc.

  • Publication number: 20120281742
    Abstract: Beamforming precoding matrix using non-uniform angles quantization. Adaptively generated feedback information is provided between communication devices that communicate using more than one communication path, link, connection, etc. With respect to feeding back different types of information having different respective characteristics (e.g., different respective probability density functions), different and respective quantization may be employed for the different types of information. For example, uniform, Gaussian, or per bit loop optimized quantization may be individually selected and employed for each of the different types of feedback information used in a wired communication system (e.g.

  • Publication number: 20120174197
    Abstract: A first device coupled to a multimedia over coax alliance (MoCA) network may receive, from a second device, an indication that a configuration button on the second device has been pushed. The first device may receive, from a third device, an indication that a configuration button on the third device has been pushed. The first device may allow the second device to be authenticated on the MoCA network if the configuration buttons of the second and third devices were both pushed within a determined amount of time. The first device may prevent the second device from being authenticated on the MoCA network if the configuration button of the second device and the configuration button of the third device were not pushed within a determined amount of time. The indication from the third device may comprise a layer 2 management entity (L2ME) message or a Protocol Information element.

  • Publication number: 20110205891
    Abstract: Systems and methods for policing a Quality of Service (QoS) flow in a MoCA network are provided. The network may include a sending node, a receiving node and a network controller. The network controller may allocate a QoS flow between the sending node and the receiving node. The sending node may request bandwidth for the QoS flow from the network controller. QoS requests have a higher priority than some other requests and may swamp the network. The sending node therefore polices its use of the network. First, the sending node computes a policing time period Tpp. Next the sending node computes a packet and bit allocation for the use of the network during a Tpp. Last the sending node sends reservation requests to the network controller when the allocation of packet or bits has not been exceeded. If any allocation has been exceeded the sending node reserves bandwidth via opportunistic reservation requests which have a lower priority than some other requests.

  • Publication number: 20100254278
    Abstract: A method for assessing channel performance in a home communication network is provided. The home communication network is operable over a plurality of channels. The home communication network includes a network controller and a plurality of nodes. Each of the network controller and the plurality of nodes is in communication over a coax backbone.

The method may also include, in response to the allocating, sending a first probe operation report message from each of the plurality of nodes to the network controller. In response to receiving the first probe operation report messages, the method may further include using the network controller to select a node to be a channel assessment operation node. In addition, the method may include selecting at least a portion of the plurality of nodes to participate in a channel assessment operation signal exchange.

  • Publication number: 20100251064
    Abstract: LDPC codes robust to non-stationary narrowband ingress noise. Particularly designed LDPC codes are adapted to address deleterious noise-effects incurred within LDPC coded signals that propagate via a communication channel (such as from a transmitting communication device to a receiving communication device). Such LDPC matrices employed for encoding and/or decoding such LDPC coded signals are composed of sub-matrices (e.g., all-zero values sub-matrices and/or CSI (Cyclic Shifted Identity) sub-matrices). The sub-matrices are generally uniform in size and square in shape. Based on certain operational conditions, such as communication channel noise, various operations within a communication device are adaptively modified (e.g., signaling, modulation, demodulation, symbol mapping, metric generation, decoding, etc.).

  • Publication number: 20100246586
    Abstract: Systems and methods for transmitting packets over a network of communication channels are provide. A system according to the invention may include first and second nodes in communication with a coax backbone. The first node may further include a retransmission buffer. The system may also include a network access coordinator operative to coordinate access of the nodes to the coax backbone. In a time period at least one first packet is transmitted by the first node to the second node. The first packet may include an indication that retransmission service is applied. The first packet may also include a indication of the length corresponding to the packet. If, during the first time period the packet is not received by the second node, the second node is operative to send a retransmission request to the network access coordinator.

  • Patent number: 7697522
    Abstract: A system for transmitting packets over a home network of communication channels, typically coax cable, including a set of nodes, at least one having a packet aggregation functionality in which the node forms an aggregation frame by aggregating one or more packets which have accumulated at the node and transmits the frame. A network coordinator coordinates access of the nodes to the channels. At least one node is operative to inform the coordinator when it has formed an aggregation frame comprising a plurality of packets and to provide the coordinator with comparison information comparing different transmission possibilities for the frame. The coordinator, preferably responsively, determines whether, when, and which of, the aggregated packets can be transmitted.
