In some implementations, nodes which determine that they are unable to support ECSs transmit an indicator which notifies other nodes that admission of the NCS is denied by that node. By contrast, if none of the nodes transmit an indicator during the temporary admission period, then the NCS is “admitted” to the MANET and the source node is permitted to keep transmitting the NCS, a variation thereof or another new communication stream. | 2009-04-30 |

If the access terminal fails to establish the session, the access terminal selects a new acquisition channel from an acquisition table other than the acquisition table from which the original acquisition channel was selected. The access terminal then repeats the above steps in order to attempt to establish a session, beginning with acquisition on the new acquisition channel. In this way, the number of unsuccessful session establishment attempts resulting from back end network failures is typically reduced, shortening the time to successful session establishment, reducing power consumption by the access terminal, and lessening interference due to unsuccessful attempts to establish a session. | 2009-04-30 |

The device's user selects one of the WAPs (e.g., a “legacy” WAP) from the list. The WPS-enabled WAP receives the user's selection and sends, to the device, the configuration information for the selected WAP. The user's device configures itself, using the configuration information, to interact with the selected WAP. Thereafter, the user's device can access a network through the selected WAP, even if the selected WAP is a “legacy” WAP. | 2009-04-30 |

Each mailbox unit is connected to each external interface unit. The units are implemented on PCs (personal computers) having memory controllers and move the packets through the router close to or at the IPO (input/output) rate of the memory controllers. | 2009-04-30 |
| 20090109969 | Dynamic Routing of Wideband and Narrowband Audio Data in a Multimedia Terminal Adapter - A multi-media terminal adapter includes a narrowband SLIC and a wideband SLIC. A DSP circuit is configured to encode a VoIP data stream and to transmit the encoded VoIP data stream to the wideband SLIC or the narrowband SLIC. A processor determines whether the VoIP data stream includes narrowband audio data or wideband audio data, and instructs the DSP circuit to transmit the encoded VoIP data stream to the wideband SLIC or the narrowband SLIC depending on whether the received VoIP data stream includes narrowband audio data or wideband audio data. | 2009-04-30 |
| 20090109970 | Network system, network management server, and access filter reconfiguration method - Provided is a network system, comprising: a plurality of network devices; a network constructed from the plurality of network devices; and a management server managing the network. The plurality of network devices include a first network device in which a filter assigned as a target of reconfiguration is set and a second network device coupled at a lower level of the first network device. The management server obtains topology of the network from the plurality of network devices; reconfigures, by referring to the obtained network topology, the filters of the first and second network device such that a range in which a packet can be forwarded through a reconfiguring filter set in the first network device is made equal to a range in which a packet can be forwarded through the filter set in the second network device; and sets the reconfigured filters into the network devices. | 2009-04-30 |
| 20090109971 | AFTER TRANSMISSION RETURN SIGNAL - A method includes transmitting a next transmission after an inter-frame period after a previous transmission, wherein the inter-frame period is long enough to allow a return signal responding to the previous transmission. A network device includes a receiver to receive a transmission from a source device and a transmitter at least to transmit a return signal to the source device indicating successful receipt or lack thereof of the transmission during a return period forming part of an inter-frame period after the transmission. | 2009-04-30 |
