摘要： The invention relates to a system and method of dispersion measurement in an optical fiber network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.

摘要： A method and apparatus are provided for allocating resources in a communication network including at least one access point exchanging data with at least one terminal connected thereto, and managing at least two communication channels. The method in the access point implements a phase of associating and authenticating a terminal with the access point, including a step of associating a unique identifier with the terminal, and a phase of managing the assembly of channels. The phase of managing includes implementing a reference table associating one of the channels to a terminal identified by the unique identifier thereof, including the following steps: detecting a switching of a terminal connected with the access point, from an initial channel to a destination channel; and updating the reference table to associate the unique identifier of the terminal to the destination channel.

摘要： A method and device are provided for transmitting data packets to an access network with sharing of a multiband channel among stations. A first band is referred to as a “transmission” band, and a second band is referred to as a “signaling” band. A station accesses the channel for transmitting data of a stream after using a counter to decrement a backoff value. The method includes: receiving backoff counts sent successively over the signaling channel by the various stations relating to their various streams; comparing the backoff counts with one another in order to detect identical values; and in the event of there being identical values between a plurality of stations, determining at least one new backoff count value that is different from all the others.

摘要： A technique that minimizes false triggering of an electrostatic discharge (ESD) protection circuit is disclosed. In an embodiment, the resistor-capacitor (RC) time constant of an ESD trigger element is reduced during normal operation minimizing the risk of false triggering. Circuit layout area is saved without the need of a timeout circuit associated with releasing a device maintaining a trigger state (i.e., a trigger latch). A RC time constant for triggering is set in an operational context according to conditions of usage and desired application of the ESD protection circuit.

摘要： A method for transmitting data packets in a communication network using a plurality of radio frequency channels, at least two of the radio frequency channels being concatenated to form a concatenated channel. The method includes: acquiring and reserving at least one of the channels from the concatenated channel, thus reserving a first frequency band for transmitting data packets to a first target device; acquiring and reserving channels from the concatenated channel that were unreserved during the first step of acquisition and reservation, thus reserving a second frequency band for transmitting data packets to a second target device; generating a preamble specific to a selected data packet, which includes a simultaneous transmission indicator on the first and second frequency bands; and simultaneously transmitting the data packets on the first and second frequency bands, from the selected packet and the specific preamble, before the selected packet on the second frequency band.
