We present two resource reservation schemes which are intended for different real-time VBR video application scenarios with different resource requirements. The static scheme makes a CBR reservation based on a target rate while the dynamic scheme relies on the RCBR service to achieve an efficient resource utilization. In each scheme, a traffic smoothing process is employed to regulate the video traffic such that it ensures video display continuity and meets the resource restrictions imposed by the application or the network. The smoothing algorithms are directly adapted from some smoothing optimization methods for stored videos with additional considerations of the real-time requirements. Quantization controls are initiated only when the smoothing results are known or are likely to violate the resource restrictions in the future
