Evaluating switching techniques for binary n-cubes under SPP traffic

Analytical models are cost-effective and versatile tools for evaluating system performance under different design alternatives. This study presents an analytical performance model for pipelined circuit switching (PCS) in binary n-cube networks in the presence of bursty traffic, which is modeled by a switched Poisson process (SPP). The validity of the model is demonstrated by comparing analytical results to those obtained through simulation experiments of the actual system. This model and that proposed by Min et al. for wormhole switching (WS) are then used to investigate the relative performance merits of PCS and WS under bursty traffic.
