Abstract:
1. A method to detect errors at a receiving node comprising: receiving a data set comprising: a plurality of data segments, each of the plurality of data segments having a descriptor; a data packet for each of the plurality of data segments, each of the data packets including the data segment and the descriptor for each of the plurality of data segments, wherein a size of the data packet is 2 kilobytes and the descriptor comprises a data sequence identifier; a source cyclic redundancy check (CRC) code for each of the data packets, wherein a size of the CRC code is 4 bytes; storing each data packet in a 64 kilobyte memory block at a receiving node; storing the source CRC codes as a source CRC table in a 128 byte memory block at the receiving node; computing a received CRC code for a first data packet; determining whether the received CRC code for the first data packet is in the source CRC table; and using the first data packet when the received CRC code for the first data packet is in the source CRC table by storing the data segment of the first data packet in receiving storage in an order specified by the data sequence identifier of the first data packet.
