Abstract
In general, the invention is directed to creating and placing an error correction code in a cell for error correction of data or frames carried by that cell or related cells. When frames of data arrive at a gateway between two networks, the frames of data are mapped into cells used for transport. Error correction codes are generated and placed into the payload of each transport frame or cell. The transport cells encapsulating the data frames are carried over the network to another gateway, wherein the transport cells are processed and corrected for errors based on an error correction code in one of the transport cells.Providing the error correction code allows for the correction of lost or corrupted information during transport without requiring retransmission of data. When multiple frames of data are mapped into a transport cell, error correction for one transport cell will minimize the need for retransmission of multiple data frames.
