Abstract
A scheme for error control on AAL in ATM networks capable of realizing a reliable communication with a high throughput and a low latency. On AAL, the segmented data are sequentially written into each column of a matrix shaped data region in an interleaver, while variably setting a last column of the data region in the interleaver. Then, an error control code for the data up to the last column in each row of the data region in the interleaver is obtained and written into a corresponding location within a matrix shaped error control code region in the interleaver. The contents of each column of the data region and the error control code region in the interleaver are then read out, and a prescribed header/trailer is attached to a prescribed number of columns of the data and/or the error control codes read out from the interleaver to form a data unit. Each data unit is sequentially given to a lower layer such that data units are transmitted in forms of ATM cells through the ATM network and an error correction using the error control codes can be carried out for the data at a receiving side when an error occurs during data transfer.
