Abstract :
A cell loss recovery method to be applied to the virtual paths (VPs) of asynchronous transfer mode (ATM) networks is introduced. The method uses forward error correction (FEC). Its advantages over conventional methods on virtual circuits (VCs) include reduced coding/decoding delays and facility sharing. In addition to consecutive cell loss compensation, another feature of this method is that cell loss compensation facilities are only required at VP terminating nodes. When a cell is discarded due to buffer overflow, successive cells also tend to be discarded. Performance estimations show an outstanding reduction in cell loss rate
