Abstract
A host computer connected over a wide area network system to a client computer interleaves N groups of parity protected packets in order to recover from single or multiple error events of length T. Each of the N groups of data are comprised of M data packets plus one parity packer generated by the modulo-2 sum of data in like positions of the data packets within the group. An error event of length T affects only one packer in each of the N groups, allowing recovery of the lost data, assuming that N or less packets in succession are lost.
