Under the current condition of the VLSI technique, 8 X8 switches used in MNs have the best performance/cost ratios. Based on Delta network, Baseline network and current VLSI technique development level, this paper puts forward the idea of a new family of MNs using 8 X8 switches which is called Super Recursive Baseline Interconnection Network (SRB), expounds its network topological properties and routing techniques, makes performance analysis in this network, and proves that it has superior qualities in network pass rates, bandwidths and performance/cost ratios, etc. Finally, this paper states that SRB is a family of Multistage Interconnection Network simple in routing, superior in performance/cost ratio, and easy in expanding.
