ABSTRACT:
In a packet switching system, a source node divides a variable length packet into a plurality of cells having a predetermined length, and sequentially sends the cells toward a destination node via a first bus controller accommodating the source node, an ATM (Asynchronous Transfer Mode) switch, and a second bus controller accommodating the destination node. The second bus controller detects and stores the last cell from the source node. The destination node generates receive response data for every incoming cell by hardware control to show whether or not the cell has been normally received, and returns the response data to the second bus controller. In response, the second bus controller generates a response cell by hardware control and returns it to the source node via the ATM switch and first bus controller. This allows the source node to determine rapidly whether or not the receipt at the destination node is normal cell by cell.
