Although asynchronous transfer mode (ATM) is used for wide-area network applications such as video-on-demand, video conferencing, and live audio rebroadcasting, asynchronous wormhole networks are a lower-cost alter- native to ATM for local area networks. This work compares the simulated per- formance of torus networks with wormhole routing, WICI routing, and WICI routing augmented by delayed deflection for congestion control. Simulation results show that WICI routing with delayed deflection continues to show good throughput even at traffic levels that would saturate a basic wormhole network.
