An Asynchronous Transfer Mode (ATM) switch (20) comprises a controller (44) which augments an ATM cell with buffering data. During cell ingress into the switch, a buffer circuit (46) connected to the controller (44) receives an augmented ATM cell and stores the augmented ATM cell in a buffer cell memory (90) in accordance with the buffering data. Upon extraction from the buffer cell memory (90), the ATM cell is routed through a switch core (22). During cell egress from the switch, the cell leaves the switch core (22), travels through a switch port (50), and is received at a second buffer circuit (72). The second buffer circuit (72) stores the augmented ATM cell in a cell buffer memory (92) in accordance with the buffering data. |
