Abstract:
A cell switching method in an ATM switching system in which each of a plurality of ATM cells received from a plurality of incoming highways is transferred to one of a plurality of outgoing highways, said cell switching method comprising the steps of:converting a received ATM cell to an internal cell, said internal cell having an error correcting code attached thereto;partitioning said internal cell into a plurality of partial cells;adding identical routing information to each of said plurality of partial cells;distributing said partial cells with said routing information to a plurality of ATM switches;independently performing, at said ATM switches, switching of partial cells distributed thereto in said distributing step;receiving switched partial cells from the respective ATM switches and performing, for the internal cell, error detection and correction based on said error correcting code; andre-converting said internal cell, for which the error correction has been performed, to an ATM cell and transferring it to a corresponding outgoing highway.
