Routing Statistics for Unqueued Banyan Networks

Unknown author (1990-09-01)

Banyan networks comprise a large class of networks that have been used for interconnection in large-scale multiprocessors and telephone switching systems. Regular variants of Banyan networks, such as delta and butterfly networks, have been used in multiprocessors such as the IBM RP3 and the BBN Butterfly. Analysis of the performance of Banyan networks has typically focused on these regular variants. We present a methodology for performance analysis of unbuffered Banyan multistage interconnection networks. The methodology has two novel features: it allows analysis of networks where some inputs are more likely to be active than others, and allows analysis of Banyan networks of arbitrary topology.
