【Abstract】 Performance analysis is an important aspect in the designing of admission control mechanism. In order to evaluate the admission control mechanism, we should get the critical data in the experiments, which is difficult in real network. Network simulation is an effective method in performance analysis. network design etc. In this paper, we design and develop the traffic generating and admission control modules in NS-2 simulation platform. Experiment is carried out using those modules to evaluate the admission delay and admission probability. Last , we discuss their future trends and present several issues remained to be studied by combining the experiences of our research.更多还原
