Performance evaluation of BIN/ABIN networks in buffered/unbuffered packet-switched environments

The performance of various interconnection networks (INs) is evaluated and compared in this paper. The throughput and complexity of the buffered and unbuffered Baseline IN simple and augmented), in packet-switched environments, are compared with those of the crossbar, the (un)buffered BIN, and the single-buffered BIN. It is shown that adding buffers to a network improves its throughput. It is also shown that augmentation improves the performance of a network more than buffering does for networks with up to seven stages, whereas buffering is recommended for larger networks.
