  • Patent number: 8213447
    Abstract: The present invention enables the coupling and decoupling of multiple processing devices to a network without disrupting the network. In an embodiment, the invention provides a switch having a network port and several initiator ports each configured for coupling to a processing device. The switch is configured to route data from the network port to the initiator ports and from the initiator ports to the network port. A management agent facilitates operation of the switch by processing port initializations, replying to device registration requests, and processing predetermined unsolicited discovery commands. During operation, the management agent enables configuration changes caused, for example, by the coupling and/or decoupling of processing device to initiator ports.

  • Patent number: 8213353
    Abstract: This document proposes soft activation and inactivation of (network) repeaters that are, for example, activated on an as-needed basis. With soft activation, repeater gain ramps upward at a controlled rate, thereby avoiding rapid changes in interference caused by the repeater. Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation/inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater.

  • Patent number: 8208440
    Abstract: The present invention relates to performing handover of a mobile terminal to a network. Preferably, the present invention generates a first heterogeneous protocol message from a heterogeneous network handover module to a medium access control (MAC) of the mobile terminal, wherein the heterogeneous network handover module is configured to provide convergence of information from at least one network interface module associated with one of a homogeneous and heterogeneous network into a unified presentation. A management request associated with a handover process is then transmitted to a serving network, wherein the management request comprises the first heterogeneous protocol message. Accordingly, messages can be remotely exchanged via a radio section between heterogeneous network handover modules of a mobile terminal and a serving network. Therefore, messages are transferred faster and media independent handover is performed more quickly.

  • Patent number: 8189547
    Abstract: A self-configuration method for access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more transmitting access devices, the beacons being transmitted and received using a plurality of different channels available to the wireless network. The method records radio frequency (RF) data associated with the received beacons, and processes the RF data to select, from the plurality of different channels, a respective channel for each of the access devices. In addition, the RF data is processed to adjust transmit power levels for the access devices. The selected channels and adjusted transmit power levels are then used as configuration settings for the access devices.

  • Patent number: 8189597
    Abstract: A pipeline scheduler provides a minimum bandwidth guarantee by transporting cells from an input port to an output port in a two-phased approach. Cells that conform to a minimum cell rate (MCR) are selected from queues at the input port and arranged into supercells for transport to the output port, followed by nonconforming cells, to guarantee fairness by using scheduling modules to build the supercells first for conforming cells, and then for nonconforming cells. Reservation vectors are used to permit the same time slot of the next frame to be reserved by a first queue, and the same time slot of the following time frame to be held for reservation by a second queue, to ensure equal time slot access by the first and second queues over successive time frames.

  • Patent number: 8184584
    Abstract: In wireless communication using links with neighbor wireless devices, a wireless device calculates ratios of throughput to maximum throughput for the links and calculates the costs of the links using the calculated ratios. Then the wireless device finds, for each destination, a route in which the sum of such calculated link costs is the minimum, and sends a packet to the destination using the route. As a consequence, routing can be done according to an isotonic, easy-to-implement routing protocol.
