Abstract
An apparatus for supervising and controlling ATM traffic, and which collects traffic information, comprises a cell detecting unit for outputting a cell detecting signal whenever detecting a user information cell flowing through an ATM switch unit, an idle cell detecting unit for outputting an idle cell detecting signal whenever detecting an idle cell flowing through an ATM switch unit, a cell counting unit for counting the cell detecting signals output from the cell detecting unit, an idle cell counting unit for counting the idle cell detecting signals output from the idle cell detecting unit, an idle cell rate detecting unit for detecting an idle cell rate from both counts output from the cell counting unit and the idle cell counting unit at regular intervals, and a control unit for performing the operation of traffic control in accordance with the idle cell rate provided from the idle cell rate detecting unit at regular intervals.
