ABSTRACT:
The object of the invention is to provide a method and a circuit for a crosspoint buffer-type self-routing switch circuit in an ATM switch that allows a switch of higher speed and greater efficiency with a more compact hardware construction and without complicated circuit configuration or operation.
In the ATM switch of the present invention, a collision of cell destination address detection section that detects and counts collisions between input cells having the same output destination and an accumulated waiting time calculation section for each output port are provided between the input lines and a crosspoint buffer section, the loss number due to collisions at the collision of cell destination address detection section and accumulated waiting time are simultaneously stored in the crosspoint buffer together with the cells, and, by making the accumulated waiting time and the loss number due to collisions between input cells accord with the waiting time upon reading out and transmitting the cells from the crosspoint buffer, sending timing that is automatically free of collisions can be achieved when reading out cells.
