In this paper, in addition to the Single Segment (SS) admission control first described in [7], we propose two new types of admission control schemes called Segmental Re‐tuned (SR) admission control and Multiple Segment (MS) admission control for variable‐bit‐rate video streams under various video server architectures. The basic approach to the algorithm development is first to formulate each problem as a mathematical problem and then to identify special structures and properties for such formulations so that optimal real‐time algorithms can be developed. In computational experiments, it is shown that the proposed algorithms for the considered video server architectures, compared with the traditional admission control scheme based upon the peak frame size, typically achieve over 175-200% improvement in the system throughput. In addition, the new proposed MS scheme performs 5-25% better than SS and SR schemes.
