This self-routing switching network consists of simple 2*2 switching elements, distributors, and buffers located between stages and in the output ports. The proposed switching requires a speedup factor of two. The structure and the operation of the switching network are described, and its performance is analyzed. The switch has log/sub 2/N stages that move packets in a store-and-forward fashion, incurring a latency of log/sub 2/N time periods. The performance analysis of the switch under uniform traffic pattern shows that the additional delay is small, and a maximum throughput of 100% is achieved as buffering is increased. 收起
