The authors propose an architecture for asynchronous-transfer-mode (ATM) switching which is based on a self-routing switching principle. It is constructed by connecting self-routing switching modules in a three-stage link configuration, an architecture called multistage self-routing (MSSR). The cell-loss probability and delay have been evaluated. The results show that even when voice signals occupy 70% of the transmission capacity and burst data occupy 20%, the average delay per node is less than 60 mu s and the cell-loss probability is less than 10/sup -9/. This shows that this system has a larger traffic capacity than existing circuit switches, which are designed for an average loading of 70 to 80%.
