Abstract

The Clos interconnection network is one of the earliest multistage interconnection networks.Recently, a necessary condition on the number of middle-stage switches required to achieve broadcastcapability was presented [ Tech. Rep. JHU90/04 ( Computer Science Department, Johns Hopkins University, Baltimore, Md, 1990)]. A linear time control algorithm that determines whether a new input request is feasible or not was also provided. Here, the special characteristics of optics are used to provide a constant time parallel realization of the network control setup. This permits a reconfigurable Clos broadcast network.
