Abstract
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.
