Abstract
A congestion control unit and method in an ATM network is disclosed. The congestion control unit includes a congestion detector, a congestion controller and a routing controller. The congestion detector receives the measured number of cells generated from an output link through an ATM switch module, transmits the measured number of cells to an adaptive connection admission control unit, and detects the state of the output link by use of a utilization of a cell transmission link. The congestion controller receives congestion state information from the congestion detector and receives a cell loss ratio through the ATM switch module. The congestion controller transmits a backward resource management cell to a user or generates a routing control request signal so as to assign the load of the input traffic to another affordable link, and supplies a monitor parameter to the ATM switch module. The routing controller receives the routing control request signal from the congestion controller, and supplies routing information on an affordable link of the same destination to the ATM switch module.
