  • Error correction and loss recovery of packets over a computer network
    Patent number: 6000053
    Abstract: A method of recovering a lost or corrupted data packet of a plurality of data packets transmitted by a transmitting computer system to a target computer system over an unreliable computer network. In one embodiment, the transmitting computer system generates parity information by padding the plurality of data packets to the length of the longest data packet with a suitable bit pattern. The parity information is then generated using a suitable algorithm, such as an exclusive OR (XOR) operation. The parity information and the packet lengths of the data packets are used to form the parity packet. The transmitting computer system then sends both the data packets and the parity packet to the target computer. If the target computer system detects a lost or corrupted data packet, the target computer attempts to reconstruct the lost or corrupted data packet. The received uncorrupted data packets are padded with the suitable bit pattern described above.
