【摘要】 ATM 网络信息拥塞是制约网络发展的一个重要因素。本文针对单瓶颈节点网络,考虑两个饱和非线性因素,制定控制规则,寻找优化参数,设计模糊控制器。仿真结果表明在回路时延和可用带宽大幅波动的情况下,系统仍具有较好的控制效果,保证服务质量,进一步验证了算法的有效性。更多还原

【Abstract】 Information congestion is an important factor that restricts the development of ATM networks. In this paper, single bottleneck node network is considered. With two saturation factors, we make control rules, find optimal parame- ters and design the controller. The simulation results show good performance under the conditions that round-trip time and available bandwidth exist large oscillation. The quality of service is guarantee and the validity of fuzzy control scheme is verified.更多还原
