摘要： A data synchronizer is provided for synchronizing data across two different clock domains in a manner that avoids additive jitter. The data synchronizer includes a synchronizer inputting a sampling clock and a data clock, and outputting an edge pulse. A synchronizer jitter lockout circuit inputs the edge pulse and the sampling clock and outputs a data sampling enable signal which never coincides with a data transition.

摘要： A method and computer program product for providing RTP suppression across a DOCSIS network. An index number and a set of rules are sent to a receiver. The index number indicates the type of header suppression technique (i.e., RTP header suppression) to be performed, and the set of rules define how to recreate the RTP packets on the receiving end. At least one complete RTP packet is transmitted upstream for enabling a receiver to learn the RTP header. Subsequent RTP packets are transmitted upstream for reconstruction at the receiving end. The subsequent RTP packets are comprised of delta values representing fields that dynamically change from packet to packet in an RTP header.

摘要： A system, method and computer program product is provided for mitigating the effects of burst noise on packets transmitted in a communications system. A transmitting device applies an outer code, which may include, for example, a block code, an exclusive OR (XOR) code, or a repetition code, to one or more packets prior to adaptation of the packets for transmission over the physical (PHY) layer of the communications system, wherein the PHY layer adaptation may include FEC encoding of individual packets. The outer coded packets are then separately transmitted over a channel of the communications system. A receiving device receives the outer coded packets, performs PHY level demodulation and optional FEC decoding of the packets, and then applies outer code decoding to the outer coded packets in order to restore packets that were erased during transmission due to burst noise or other impairments on the channel.

摘要： A method, apparatus and computer program product is provided for classifying a target data packet entering a network interface. For each of a plurality of received classification parameters, at least one program module is generated. Each program module tests a pre-defined field(s) of the target data packet for adherence to the classification parameter(s) with which the program module is associated. A pre-classification header is generated wherein an indication is made of where one or more pre-defined fields are located in the data packet if the field is present. Maintaining locations of the pre-defined fields of the target data packet in the pre-classification header prevents having to recalculate the addresses of the pre-defined fields of the target data packet. Eliminating the need for re-calculating the addresses of the pre-defined field(s) can allow the classification process of the present invention to obtain an optimal execution speed.

摘要： Embodiments herein provide systems and methods of transferring data in a communication system. An embodiment transfers data by assigning a portion of data among groups of channels coupled to a remote node, such assigning being based on the respective flows to which the portion is associated. The portion of data across is at least two channels in the assigned group of channels, and the split portions are transferred substantially simultaneously among the channels to which they are assigned.

摘要： A system for spur cancellation comprises an input, an output, a memory, and a summer. A value corresponding to an energy level of a spur is stored in the memory. The summer is configured to receive an input signal from the input, to receive the value from the memory, to subtract the value from the input signal, and to convey an output signal to the output. The output signal is a difference of the value subtracted from the input signal.
