Abstract
Multicasting of an ingress cell received at one of a plurality of input ports is provided through a multistage switching network to one or more of a plurality of output ports. An ingress cell including a data payload and information identifying output ports of the network is received at one of the input ports of a first stage of the network. A determination is made of the minimum number of first output ports of the first stage of the network to which a single copy of the ingress cell is to be outputted to enable the ingress cell to reach all of the identified output ports. The single copy of the ingress cell is then routed to the minimum number of first output ports of the first stage of the network.
