Abstract
A method, apparatus, and computer program product for responding to congestion levels in a communication system by rate adaptation. A congestion condition is indicated by marking data packets. In response to receiving an indication of congestion, a data rate is reduced. A rate reduction inhibit timer is started, and further rate reduction is initiated if congestion is indicated after the rate reduction inhibit timer has expired. A rate increase timer is used to initiate a rate increase if no indication of congestion is received during a rate increase time.
