Embodiments of the present invention are directed to providing a method and system for call admission control and preemption of multiple bit-rate applications in a digital communication system. Multiple bit-rate applications such as streaming video can specify a Quality of Service (QoS) profile having multiple levels. When there are insufficient resources in the network to support an incoming multiple bit-rate call, the system determines whether, by reducing the bit-rate of the incoming call or by preemption of lower priority components of existing calls, enough resources can be recovered to support the incoming call.
