    摘要： In order to reduce the cost of the gateways as well as to ease the management and administration of the gateways, the execution of the network functions is deported in commodity servers under physical and logical control of the ISPs. In the vCPE model, the traffic transmitted from/intended to a gateway goes through a middlebox server or network device performing, among other functions, a NAT function and a firewall function on the data packets continuing the traffic transmitted from/intended to the gateway. For reliability, each master middlebox server is seconded by a slave middlebox server which replicates traffic handled by the master middlebox server. Such a solution is costly and not sustainable. The invention provides a method for remotely performing a network function by a processing unit associated to one processor core of a multicore processor embedded in a network device.

    摘要： In a context of a packet forwarding device, operating packet field translations as packets are forwarded between two networks, a salient idea is to allocate deterministically translated identifiers (such as for example port numbers in IPv4 NAT), in the packet forwarding device, the allocation using a deterministic operator depending only on data information present in or derived from the packet to forward. The data information of the packet on which the deterministic operator is applied are for example a source address of a communication protocol and an identifier of an encapsulated communication protocol. More generally the data information (for deterministically allocating translated identifiers) characterize the packet as belonging to a particular data flow and/or logical connection. Thanks to this salient idea, in a context of recovery procedure, whenever a backup device becomes active and receives packets from an existing logical connection / data flow, it can recover the decision that was taken by the former packet forwarding device without requiring explicit information from the former packet forwarding device, advantageously recovering the state from the departed packet forwarding device. No replication protocol or pro-active state replication is needed between a packet forwarding device and a backup device, advantageously saving protocol complexity, implementation cost, memory, processing resources and network bandwidth.

    摘要： A radio frequency identification (RFID) reader identifies in which room among several rooms the RFID reader is more likely to be located. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving RF signals generated in corresponding pairs of RFID tags. The RFID tag pairs are attached to corresponding regions of each of the rooms. Each of said RFID tag pair including a first RFID tag and a second RFID tag that are spaced from each other by a distance that is larger or equal to »/4 and smaller than or equal to »/2 with respect to a frequency of a responding RF signal originated in the pair of RFID tags. A processor selects a larger RSSI of the RSSI's of the signal pair. The processor determines a corresponding sum of the RSSI's selected from each signal pair associated with each room. The processor evaluates in accordance with determined sums, the location in which said RFID reader is more likely to be located.
