In our paper we present a bifurcated buffer banyan ATM switch concept. Bifurcated input buffering was proposed previously for switches with input buffers. We expanded it to buffer a banyan ATM switch with internal input buffers. Here, we give a detailed description of the proposed switch performance analysis, based on the algorithm described in [3]. Our proposition advantages over the simple input buffer banyan are higher throughput and lower cell loss probability. We found that buffer size b=20, for input load p<0.78, is enough for obtaining the required ATM switch performance levels no matter the switch size. It means that cheap and simple input buffering is possible in bifurcated banyan ATM switching.
