20110286280 | Pulse Control For NonVolatile Memory - This disclosure provides a nonvolatile memory device that uses pulsed control and rest periods to mitigate the formation of defect precursors. A first embodiment uses pulsed bitline control, where the coupling between a memory cell channel and a reference voltage (selected in response to the bitline) is pulsed when it is desired to change state in the associated memory cell. Each pulse may be chosen to be less than about (20) nanoseconds, while a “rest period” between pulses typically is chosen to be on the order of about a hundred nanoseconds or greater (e.g., one microsecond). Because bitline control is used, very short rise times can be enabled, enabling generation of pulse durations of (50) nanoseconds or less. In other embodiments, these methods may also be more generally applied to other conductors (e.g., wordline or substrate well, for program or erase operations); if desired, segmented wordlines or bitlines may also be used, to minimize RC loading and enable sufficiently short rise times to make pulses robust. | 2011-11-24 |

20110286324 | Link Failure Detection and Traffic Redirection in an Openflow Network - Failure detection and traffic redirection are implemented in an OpenFlow switch. Link failure detection packets, such as Bidirectional Forwarding Detection (BFD) packets, are periodically sent out on links to peer OpenFlow switches, such as via the Multi-protocol Label Switching (MPLS) Transport Profile (MPLS-TP). Link failure detection packets are received from the peer OpenFlow switches on the links, and monitored. A link failure is detected if no incoming link failure detection packets are received on a link for a predetermined interval. In the event of a link failure, traffic is redirected from the failed link to a backup link by altering entries on a flow table of the OpenFlow switch. | 2011-11-24 |
20110286325 | HYBRID SATELLITE AND MESH NETWORK SYSTEM FOR AIRCRAFT AND SHIP INTERNET SERVICE - A hybrid satellite-mesh network including a ground segment, a mobile segment and a satellite segment provides high bandwidth communication between mobile platforms and the Internet. The satellite segment is used only when mesh network communication links between mobile segment nodes and ground segment nodes are unavailable. Mobile segment nodes can function in either an access terminal mode or an access point mode to communicate with other mobile segment nodes according to a routing algorithm in a mesh portion of the network. Mobile segment nodes employ adaptive frequency reuse, link level date rate adaptation, link level power control and adaptive beam forming antennas. | 2011-11-24 |
20110286326 | Communication system, forwarding node, path management server, and communication method - A communication system comprises: a path management server that generates a plurality of forwarding path information items each includes a sequence of identifiers, each of which identifies a communication interface provided in each of a plurality of forwarding nodes on a forwarding path in a data forwarding network or a link established between the forwarding node and a neighboring node thereof; and a forwarding node that, in accordance with at least one of the plurality of forwarding path information items, executes a packet forwarding processing of a packet with a header including the plurality of forwarding path information items. | 2011-11-24 |
20110286327 | Method, Apparatus, and System for Processing Radio Link Failure - A method for processing radio link failure (RLF) is disclosed. When a user equipment (UE) communicates with a network through two or more carriers, if a downlink RLF occurs on at least one of the two or more carriers, the UE determines whether there is a carrier among the two or more carriers on which no downlink RLF occurs. The UE stops sending information on an uplink dedicated physical control channel (DPCCH) of the carrier on which the downlink RLF occurs if there is a carrier on which no downlink RLF occurs. | 2011-11-24 |
20110286328 | SYSTEM MANAGEMENT METHOD AND SYSTEM MANAGEMENT APPARATUS - Provided is an IT system to minimize occurrence of a bottleneck on a network while effectively making use of the bandwidth of the network. A system management apparatus collects performance information from a network device, and calculates the average value, the peak hour, and the variance from the collected performance information. In response to a request for addition of a business system, the system management apparatus builds configuration patterns of a group of virtual servers configuring the business system and monitors traffic states of the paths on the network, identifies the part of the network where the traffic quality is most degraded, and determines the pattern that includes the path which has the smallest variance in the traffic based on traffic information on the part where the communication quality is degraded identified in each pattern as the requested system configuration of the business system. | 2011-11-24 |
20110286329 | ACCESS POINT, TERMINAL, AND METHOD FOR PROCESSING ACCESS CONTROL BASED ON CONGESTION LEVEL OF TRANSMISSION CHANNEL - An access point (AP) measures a congestion level of a transmission channel representing a collision probability between frames at a channel busy duration and transmits the congestion level to a terminal. Therefore, the terminal extracts a congestion level that is included in a frame that is received from the AP through a scan process for searching for an AP to which the terminal is to connect. The terminal selects an AP to connect from at least one AP based on the extracted congestion level of the transmission channel. | 2011-11-24 |
20110286330 | Hardware Filtering of Unsolicited Grant Service Extended Headers - A system and method is presented that uses hardware at a central node to determine if bandwidth being provided to a remote node in accordance with an unsolicited grant service (UGS) flow requires adjustment. In one embodiment, the hardware performs this function by comparing information in two consecutively-received UGS extended headers from the same remote device. If the information in the current and previous UGS extended headers differ, then an indication is provided to software of the central node that the bandwidth being provided to the remote node requires adjustment. | 2011-11-24 |
20110286331 | Differentiated Services Code Point Mirroring For Wireless Communications - The DSCP Mirroring System enables the automatic reuse of the Differentiated Services Code Point header by the user devices that are served by a network to enable delivery of wireless services to the individually identified user wireless devices and manage the various data traffic and classes of data to optimize or guarantee performance, low latency, and/or bandwidth without the overhead of the management of the Differentiated Services Code Point header. | 2011-11-24 |
20110286332 | Flow control apparatus, network system, network control method, and program - A flow control apparatus that sends control information to one or more switching node apparatuses, where the control information is assigned to each series of communications performed between terminal devices via the switching node apparatuses. The flow control apparatus includes an effective time setting unit that sets an effective time of the control information based on an elapsed time measured from when the terminal devices which perform the series of communications start a communication via a specific one of the switching node apparatuses, in a manner such that the longer the elapsed time, the longer the effective time; and a sending unit that sends the control information every time when the effective time has elapsed. | 2011-11-24 |
