ABSTRACT:
Multicasting is implemented in a virtual circuit switch for an ATM network by recycling data cells through the switch fabric a multiple number of times with a copy-by-two network creating an additional data cell upon each recycle to thereby satisfy the number of connection addresses in the multicast connection. Resequencing of the data cells may be implemented at the exit to the switch fabric as well as upon each recycle of data cells through the switch fabric.
