1. Switching apparatus operating at a significantly higher data rate than switching elements(SEs) which form a switching fabric and operate at a lower data rate said SEs routing data from at least one ingress source port, which receives data at said higher data rate, to egress destination ports said data being grouped in data packets having a uniform or variable plurality of digital bytes said apparatus comprising:

  • a said ingress source port including means for receiving successive data packets at said higher rate and for transmitting data via a plurality of output ports at said lower rate to said SEs;

    a sequential array of low data rate SEs each having a plurality of input ports individually connected to each said output port of said input source port said SEs and source port including means for switching source output ports successively from one SE to another available SE in response to a data packet event whereby the effective data rate from said source outputs to said SEs is at said higher data rate.
