  • Patent number: 7336680
    Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Furthermore, the architecture allows a central concentrator to support a plurality of remote devices that each have guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. The upstream and downstream bandwidth allocation can support symmetrical bandwidth as well as asymmetrical bandwidth in either direction. The architecture generally can be used to support connection-oriented physical layer connectivity between a remote device and the central concentrator.

  • Patent number: 7333501
    Abstract: A method and apparatus are presented for determining network nodes for aggregating addresses in routing information used for routing data packets over a network. Link data and reachability data are received. Link data indicates direct links between each of multiple candidate routers of a network and a different router or a network segment. Reachability data indicates a set of one or more contiguous network addresses that can be reached on each link described in the link data. A measure of possible aggregation of contiguous network addresses is determined at the candidate routers based on the link data and the reachability data. A preferred router to aggregate addresses in routing information sent between routers in the network is determined among the candidate routers based on the measure of possible aggregation at each candidate router.

  • Patent number: 7333435
    Abstract: A novel apparatus, system and method for transmitting data flows having different quality of service (QoS) attributes over a network link structured in two or more channels is provided. The method classifies arriving packets to determine their required/assigned QoS attributes and places the classified packets into one of several logical channel queues, the selected logical channel queue having an appropriate corresponding set of QoS attributes defined. A radio link controller examines the available channels and, for each channel, selects a logical channel queue whose contents will be transmitted thereon. The radio link controller determines the data transmission capacity for each channel and segments the contents of the selected logical channel to fit within the determined capacity. The selection of the logical channel queue is performed in accordance with the set of QoS attributes and thus each flow can have different QoS characteristics including priorities, reliabilities (ARQ, no ARQ, etc.).

  • Patent number: 7333499
    Abstract: A telecommunications system for receiving from a telecommunications unit a request for data from a target network address may include a request completion unit configured to receive the request for data from the telecommunications unit and to transmit a request for the data to the target address. The request completion unit may be further configured, on receiving the data from the target address, to transmit the data to the telecommunications unit via the radio link. The request completion unit, if it is determined that the request to the target address is not satisfied, may be configured to attempt to establish communication with the target address, and, if it is determined that such communication is possible, transmit an indication via the radio link to the telecommunications unit.

  • Patent number: 7333518
    Abstract: A transmission method according to the present invention is capable of transmitting and receiving a data signal and information signal among a plurality of devices by full-duplex operation, wherein, when the information signal consecutively repeats a single pattern, a different pattern is inserted between the same patterns before transmission thereof. This minimizes an adverse effect of crosstalk jitter over a transmission line susceptible to crosstalk, and reduces a margin between the transition and sampling point of a signal, thereby suppressing the cost of a CDR circuit.

  • Patent number: 7327687
    Abstract: A method and system for the capture of data files transmitted over a wired network by a data traffic generator. The mapping and/or translation of network addressing data contained within the captured data frames is such that the frames, when transferred over the wireless medium, appear to have originated from one of a population of emulated wireless stations. The mapping and/or translation of network addressing data contained in data frames received over the wireless medium directed to a specific emulated wireless station is such that the frames, when transmitted over the wired network, appear to be destined for the data traffic generator. The mapping and/or translation function is applied as frames traverse the boundary between the external data source network interface and the wireless network interface.
