Patent application number | Title | Published |
20110019538 | FAILURE RECOVERY METHOD IN NON REVERTIVE MODE OF ETHERNET RING NETWORK - Provided is a failure recovery method in a non-revertive mode of an Ethernet ring network. In an Ethernet ring network, link priorities between nodes or node priorities are determined based on media access control (MAC) addresses and the nodes having blocked ports are determined after failures are recovered from based on the priorities so that the blocked ports can be distributed. | 2011-01-27 |
20110019539 | RELAY DEVICE, NETWORK SYSTEM, ROUTE SWITCHING METHOD, AND RECORDING MEDIUM - When a failure occurs in a link or another relay device, a route control unit updates a routing table stored in a current routing table. Upon update, it acquires inhibit target route information indicating a route likely to cause a micro-loop in the updated routing table and registers it into an inhibit target table. If route update in an adjacent relay device is completed, an inhibit control unit deletes a route in which the adjacent relay device is set as a next transfer destination from the inhibit target table. A transfer processing unit determines a transfer route of a packet based on the current routing table and, if the determined transfer route is not registered in the inhibit target table, executes transfer of the packet. A micro-loop can be thereby reliably avoided when route switching in a network system where communication between plural networks is relayed by plural relay devices. | 2011-01-27 |
20110019540 | WIRELESS AD HOC COMMUNICATION SYSTEM, TERMINAL, PROCESSING METHOD IN TERMINAL AND PROGRAM TO MAKE TERMINAL EXECUTE PROCESSING METHOD - A wireless ad hoc communication system is provided in which in the case where an alternative route can not be discovered in a certain node, a restoration is attempted in an intermediate node instead of deleting all routes up to a transmission source. | 2011-01-27 |
20110019541 | METHODS AND APPARATUS FOR IMPROVING POWER EFFICIENCY AND LATENCY OF MOBILE DEVICES USING AN OUT OF BAND WIRELESS RESOURCE - Methods and apparatus of using a licensed spectrum to transmit data when an unlicensed spectrum is congested are disclosed.

20110019543 | SOFT PACKET DROPPING DURING DIGITAL AUDIO PACKET-SWITCHED COMMUNICATIONS - A method of packetizing digital audio information for packet-switched communications includes separating a digital audio sample into at least one most significant bit and at least one least significant bit. The at least one most significant bit of the digital audio sample is placed into a variable-length most significant bit packet having a high transmission priority for transmission over a packet-switched network in which at least one node receives the packet and independently determines how to route the packet. The at least one least significant bit of the digital audio sample is placed into a variable-length least significant bit packet having a low transmission priority for transmission over the packet-switched network. Prioritization of packets as having a high transmission priority or low transmission priority is independent of speech characteristics of digital audio samples with elements contained therein. | 2011-01-27 |

The method includes the steps of: sending by the client a request message requesting a service to the server using a first public network address associated with the server; processing the request message at an intermediate logic unit logically positioned between the client and the server; and receiving an alert signal at the intermediate unit. Upon receipt of said alert signal, the method provides for: mapping the private network address of the server to a second public network address associated with the server; and instructing the client to send the request message to the second public network address of the server, routing to the server only request messages directed to the second public network address. | 2011-01-27 |

20110019549 | ADMISSION CONTROL IN A PACKET NETWORK - In embodiments of the invention when a session request is received the value assigned to that session is compared to present congestion costs in the network at the present time. If the value of the session exceeds the cost then the session is accepted; otherwise it is rejected. It is possible to show mathematically that, provided this strategy is used for all session requests, then, when demand exceeds supply for a given resource, the congestion measurement for that resource rises to become equal to its shadow price. Here, in a model of a capacity constrained network, the shadow price of a capacity constraint is the cost to other users of using one unit of capacity. Congestion measurements can therefore be used to provide a “cost” (to other users) of admitting the flow to the network, which can then be compared against the “value” (to the network operator) of admitting the flow during the admission control evaluation. Additionally, this “cost” vs. “value” comparison can be used for path selection, as well as any other resource management decision. For example, in particularly preferred embodiments a session is not only admitted based upon the cost value comparison, but is also assigned to a particular path which maximises value minus cost. | 2011-01-27 |

20110019551 | FLOW STATE AWARE MANAGEMENT OF QoS WITH A DISTRIBUTED CLASSIFIER - Packet network node and method of operating packet network node. Conventional packet network nodes react to congestion in packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In the described system, indiscriminate packet discards are prevented by causing packets to be discarded on lower priority flows and flow aggregates. Further action is taken to reduce the likelihood of packet discards through: (1) classification of flows that are not observable at the point in the network where flow-based packet discards are deployed, but are consuming bandwidth and signaling classification information to flow-based packet discard function or a flow-based monitoring function or network management function; (2) classification of flows making use of extended monitoring functions that are not co-located with a flow-based packet discard function, where extended monitoring functions may perform monitoring of a flow or a group of flows over a period of time. | 2011-01-27 |

20110019557 | PACKET AGGREGATION - Methods and apparatus for improving the efficient use of a wireless channel.
