摘要： Light-weight, configurable error detection in a satellite communication system that detects invalid SerDes lanes via hash codes appended to packets of data in the lanes. An indication can be passed back upstream about the invalid lane so that the lane can be reset. Error correction can be provided by reconstructing the bit data in the invalid SerDes lane based on parity information in an optional parity lane.

摘要： In a method for generating a data unit conforming to a first communication protocol, a first field and a second field to be included in a preamble of the data unit are generated. The first field includes a first set of one or more information bits that indicate a duration of the data unit and is formatted such that the first field allows a receiver device that conforms to a second communication protocol to determine the duration of the data unit. The second field includes a second set of one or more information bits that indicate to a receiver device that conforms to the first communication protocol that the data unit conforms to the first communication protocol. The first field and the second field are modulated using a modulation scheme specified for a field corresponding to the first field and the second field, respectively, by the second communication protocol.

摘要： A data storage device includes a non-volatile memory and a controller. A method includes receiving first data and second data from a host device. A first error-correcting code (ECC) codeword associated with the first data is written to a first word line of the non-volatile memory, and a second ECC codeword associated with the second data is written to a second word line of the non-volatile memory. The first ECC codeword includes a first bit and a second bit, and the second ECC codeword includes a third bit and a fourth bit. The method further includes writing parity information to a parity storage portion of the non-volatile memory that is distinct from the first word line and from the second word line. The parity information includes a parity bit that is based on the first bit, the second bit, the third bit, and the fourth bit.

摘要： Systems, methods and computer program products for facilitating the recovery of lost real-time media packets within a computer network real-time application implementing Forward Error Control (FEC), such that server performance is not affected from a CPU and memory perspective, are disclosed. In an embodiment, a conference server that is part of a communication network compliant with the Real Time Transport Protocol (RTP) is able to avoid regenerating FEC packets by not performing any FEC coding operation on the packets unless it is flagged to indicate regeneration via an FEC (e.g., Reed-Solomon) coding is necessary. Absent the flag, the conference server updates the received FEC packet as per the RTP and transmits the packet to its ultimate destination. Such disclosed systems, methods and computer program products are independent of the nature of the media being protected and flexible enough to support a wide variety of FEC techniques.
