Abstract
An ATM switch for transmitting a multicast ATM cell includes a memory, a control circuit, and a cell memory. The control circuit maintains in the memory a connection table which includes a multicast master entry and one or more multicast member entries associated with the multicast master entry. The cell memory stores one or more ATM cells, including the multicast ATM cell. The multicast master entry holds an address of the cell memory at which the multicast ATM cell is stored. The multicast member entries are linked to each other through a circular double linked list.
