摘要： 基于含有多个瓶颈节点的ATM网络模型,设计了ABR流量显式速率控制器来解决多瓶颈节点网络的拥塞问题.给出了系统稳定的充分条件,并针对变化的ABR用户数量,给出了对可控ABR用户数实时估计的方法.最后通过在不同条件下的数值仿真,验证了所设计的控制算法不但可以克服多个传播时延给控制带来的不利影响,有较强的鲁棒性,而且还可以很好地预测ABR用户数量的变化.

Abstract: Based on the ATM network model with multiple bottlenecks, an explicit rate controller for ABR traffic is designed to solve the congestion problems due to such networks. The sufficient condition for the stability of the closed-loop system is presented, and an algorithm for changeable number of ABR users is given to the real-time estimate of the number of controllable ABR users. The numerical simulation done on different network conditions showed that the proposed algorithm is able to not only overcome the adverse effect caused by multiple round-trip propagation delays but estimate the number of controllable ABR users exactly with high robustness.
