Abstract A bandwidth control mechanism is proposed for ATM networks that can control the usage of bandwidth in the presence of both connection-oriented and connection-less traffic, as well as multiple classes of connectionless traffic. The bandwidth control mechanism operates at three levels. At the topmost level, bandwidth is dynamically regulated between connection-oriented and connectionless traffic based on the utilization of each traffic type. At the next level, bandwidth is controlled between different classes of connectionless traffic, such as real-time traffic, bulk data traffic, and so on. At the lowest level, bandwidth is distributed among flows belonging to the same connectionless traffic class.
