1. An asynchronous switching node distributing cells dynamically to outputs constituting an irregular group, the addresses of the outputs of the irregular group not being mathematically related, said node including:

  • an input stage receiving cells on a plurality of inputs and receiving for each cell external routing information, said input stage adding to each cell an internal routing label conditioned by said external routing data, the label added to a cell addressed to an irregular group of outputs being selected from predetermined internal routing labels respectively identifying regular subgroups of the outputs of said node, a combination of which constitutes said irregular group, each regular subgroup including a single output or a plurality of outputs whose addresses are mathematically related; and

    a plurality of switching stages connected to said input stage, each switching stage including at least one switching element which includes means for transferring a cell received at one of its inputs to at least one of its outputs according to said internal routing label associated with said cell.
