Performance analysis of ATM banyan networks with shared queueing. II. Correlated/unbalanced offered traffic

For pt.I see ibid., vol.2, no.4, p.398-410 (1994). The paper develops the analysis of multistage banyan interconnection networks in which the switching elements are provided with a buffer shared among all the inlets and outlets of the element. Two different internal protocols are considered for the transfer of packets from stage to stage based on the presence or absence of interstage backpressure to signal the occurrence of buffer saturation conditions. The analytical model is based on the representation of the switching element state by means of only two variables. Two kinds of offered traffic patterns are considered, a bursty balanced pattern and an unbalanced uncorrelated pattern. In this latter case, the load above the average is supposed to be addressed either to a single network outlet, or to a given group of network outlets
