Abstract: For the requirements of multimedia services and quality of service (QoS) guarantee in the next-generation networks, this paper focuses on admission control (AC) based on bandwidth broker (BB) and researches four common algorithms. Analysis of different algorithms on acceptance rate, average waiting time and the performance of the network utilization are achieved based on NS-2 platform by designing simulation environments and simulation experiments. Finally, this paper concludes the comparation and evaluation of the four algorithms.
