Abstract
The techniques required to switch an ATM cell between an input adapter and an output adapter are enhanced by performing two look-up operations. The first look-up operation is performed in the input adapter which receives the cell to be switched. The first look-up operation retrieve the address of the target output port and a connection control block. The second look-up operation is performed in the target output adapter and makes use of the results of the input adapter search to retrieve the information need to complete the transfer of the cell to the target output port.
