Abstract
To enable a data packet to be broadcast from one input (I1) to a plurality of outputs (01, 02, 03, 06) the switching network comprises in each switching plane at least one stage (S2) comprising switches (SE4, SE5, SE6) adapted at least: to route multiple copies of a packet that has been multiplied on its upstream side (SE1), and to multiply a packet by forwarding it several times in succession to the same output; the copies thus created being routed subsequently by the switches (SE7, SE8, SE9) of a downstream stage (S3). The switching network has application to photonic ATM switching centers.
