摘要
为提高ATM网络流量管理性能,在随动控制结构上,进一步考虑时延因素的影响,提出了一种基于离散模型的改进的ABR流量控制算法。给出了保证时滞系统闭环稳定的参数选择方法,实现了拥塞避免和可用带宽的动态公平分配,保证了服务质量。仿真结果进一步验证了理论的正确性和可行性。
To improve the performance of traffic management of ATM networks, an improved ABR flow control algorithm was proposed based on discrete model. The effect of the delay elements was considered further with the structure of follow-up control system. The method of choosing parameters, which can guarantee the stability of closed loop time-delay system, was given. The method can avoid the congestion, allocate the available bandwidth fairly and improve the quality of service. The simulation results show that the theory is correct and practical.
