Abstract
An ATM switching apparatus and method in which delay of ATM cells is prevented and multicast is implemented are disclosed. The multicast is determined by analyzing a received cell's destination address and the transfer times value. If there are several destination addresses, the same cell buffer address is stored in the respective destination addresses. By using the cell buffer addresses stored in the respective destination address, the cells are transferred until the transfer times value becomes zero. If the transfer times value becomes zero, the cell buffer address used at this time is stored into the cell buffer address storage unit making it available to use as an address for storing a new cell.
