In this paper, we present several necessary and sufficient conditions for strictly nonblocking of three-stage multirate multicast Clos networks under various assumptions on the fan-out property of the switches. These conditions generalize results of Giacomazzi and Trecordi that were strictly nonblocking three-stage Clos networks for circuit switching multicast. In addition, two previous results in the literature will be corrected.
