[ What is claimed:] [1.] A method of recovering lost or errored packets of data transported through an ATM network having a plurality of nodes, comprising the steps of:segmenting data into blocks of predetermined size;computing vertical and diagonal parity packets for the blocks;adding the vertical and diagonal parity packets to the blocks;transmitting the blocks with the vertical and diagonal parity packets from a first node to a second node of an ATM network;selectively identifying errored or missing packets at a second node of an ATM network;selectively recovering data for errored or missing packets in an ATM adaptation layer at asecond node in an ATM network by computing the lost or missing data from the vertical anddiagonal parity packets and from other information packets; andtransmitting a corrected packet from a second node to a third node in an ATM network.
