摘要： A system and method are provided for use with streaming blocks of data, each of the streaming blocks of data including a number bits of data. The system includes a first compressor and a second compressor. The first compressor can receive and store a number n blocks of the streaming blocks of data, can receive and store a block of data to be compressed of the streaming blocks of data, can compress consecutive bits within the block of data to be compressed based on the n blocks of the streaming blocks of data, can output a match descriptor and a literal segment. The match descriptor is based on the compressed consecutive bits. The literal segment is based on a remainder of the number of bits of the data to be compressed not including the consecutive bits. The second compressor can compress the literal segment and can output a compressed data block including the match descriptor and a compressed string of data based on the compressed literal segment.

摘要： A method and apparatus for dynamically balancing traffic loads in a communications system (such as satellite communications systems), based on a control of collision rates via the real-time control of throughput of channels of the communications system (such as a real time throughput of random access channels in a satellite network). The method and apparatus generates and transmits to remote nodes or terminals an operating probability based on the determined throughput for transmission using the communications channel. Also, the method and apparatus includes receiving by at least one terminal the generated operating probability and determining by the at least one terminal a transmission probability for the communications channel based upon the received operating probability, which can further be adjusted by one or more of a received upper or lower limit of the generated operating probability or a collision rate for the communications channel.

摘要： An approach for classification of a data traffic session over a data communications network is provided. A network device receives data packets of the data traffic session. The network device determines a plurality statistical factors that characterize the data traffic session based on the received data packets. The network device analyzes the determined statistical factors in relation to a plurality of classification variables, and classifies the data traffic session as being one of a plurality of session priority types based on the analysis, wherein each of a plurality of subsets of the classification variables delineates the plurality of session priority types over a continuum with respect to a corresponding one of the statistical factors.

摘要： A measuring device comprises a processing unit, a first antenna adapted to receive a first signal, and a second antenna, adapted to receive a second signal. The processing unit comprises a baseline unit adapted to determine a baseline variance of a first variable and/or a second variable. Moreover, it comprises a variance unit adapted to determine a variance of the first variable and/or the second variable. The first variable and the second variable are each at least initially derived from at least the first signal and the second signal. The processing unit furthermore comprises an error unit, adapted to determine if a systematic error is present, based on the baseline variance and the variance of the first variable and/or the second variable.

摘要： A sampling device samples a differential measuring voltage. The sampling device comprises a first holding device, a second holding device and a multiplexing circuit, which is configured to provide a differential sample of a sampled differential signal, derived from the differential measuring voltage by sampling with a first clock signal of a first clock rate, to the first holding device, at the occurrence of each HIGH-value of a second clock signal of a second clock rate being half of the first clock rate and provide a differential sample of the sample differential signal to the second holding device, at each LOW-value of the second clock signal. The sampling device comprises a reset device configured to reset the second holding device at or after each HIGH-value of the second clock signal and reset the first holding device at or after each LOW-value of the second clock signal.

摘要： Systems and methods are provided for quality of service over broadband networks. A network device performs a probe transaction over a tunnel of a broadband network. Based on the probe transaction, parameters are determined reflecting tunnel performance, and, based on the parameters, target transmit and receive rates are determined for data communications over the tunnel. Based on the target transmit and receive rates, data communications to and from a first node of the network are regulated. When the tunnel comprises a peered tunnel, the regulation of received data communications comprises performing a set rate transaction with a peer second node of the network (the set rate transaction establishes a rate for data transmitted over the tunnel by the peer second node to the first node). When the tunnel comprises a peerless tunnel, the regulation of received data communications comprises shaping data traffic received by the first node over the tunnel.

摘要： A switch comprises a first elastic element, an actuator-element mechanically coupled to a first side of the first elastic element, and a first switching conductor, mechanically coupled to a second side of the first elastic element. The switching conductor is configured for moving between a first conductor position and a second conductor position. The actuator-element is configured from moving between a first actuator-element position and a second actuator-element position separated by a predefined actuator-element lift, thereby moving the first side of the first elastic element. The first elastic element moreover is configured for converting a movement of the first side of the first elastic element by the predefined actuator-element lift into the movement of the second side of the first elastic element with a predefined elastic force.

摘要： A satellite communications system comprises multiple satellites (e.g., a combination of LEO/MEO/GEO satellites). Multiple satellite gateways communicate over channels of the satellites with remote mobile user terminals. The mobile user terminals communicate with the satellite gateways via associated satellite terminals that interface with the satellites, or directly with the satellites. Each mobile user terminal of a first group communicates with a satellite gateway, over satellite channels, via an associated satellite terminal. Each mobile user terminal of a second group (e.g., in a remote rural area) communicates with a satellite gateway directly over satellite channels. The mobile user terminals of the first communicate with the satellite terminals locally via S-band. The mobile user terminals of the second group communicate directly over the satellite channels via Ku band or Ka Band. Each of the satellite gateways communicates over satellite channels via Ka band, Ku band, V-band or L-band.

摘要： An approach for optimizing power utilization of a satellite transponder, and thereby optimizing achievable modulation/coding schemes and data rates for terminals across the transponder beam, is provided. A signal power level is allocated to each of a plurality of carriers. The plurality of carriers are to be transmitted within a downlink beam via a transponder, each of the carriers is associated with a region of the beam, and the total power allocated to the carriers does not exceed a desired aggregate power level for the transponder. The signal power allocated to each carrier is determined relative to a gain realizable by satellite terminals within the respective beam region and assigned to receive the respective carrier, and the realizable gain of the terminals is based on locations within the beam. The signal power level allocated to each carrier is different from the power allocated to the other carriers.

摘要： Approaches for a measurement system for measuring or calibrating the amplitude of a signal of a signal generator, where the measurement system employs an ion trap, are provided. The measurement system comprises a signal generator operable to generate an output signal, and a measuring apparatus operable to determine an amplitude of the output signal. The measuring apparatus includes an ion trap operable to trap at least one ion, a signal supply device operable to supply the output signal of the signal generator to the ion trap, whereby a path of motion of the at least one trapped ion is influenced by the output signal, and a measuring device operable to determine the amplitude of the output signal based on a path of motion of the at least one trapped ion. The determined amplitude may be fed back to the signal generator for calibration purposes.
