Abstract
In an internet protocol switch including a controller and a switch section controlled by the controller, the switch section includes an input cell buffer for receiving cells input to the switch section. The output of the input cell buffer is closed during a transition time from a selected flow connection linked to the input cell buffer and the controller, to a cut through connection linked to the input cell buffer without linking to the controller. Then, after the cut through connection is established, the output of the input cell buffer is opened.
