Abstract
A packet receiving apparatus determines whether or not data to be stored in a buffer overlaps previously stored data based on information contained in a header portion of a received packet. If it is determined that the data overlaps, a checksum for the overlapping data is subtracted. If it is determined that the data does not overlap, a checksum for the data to be stored in the buffer is added.
