摘　　要：提出了一种新的融合速率和凭证流量控制方法、无丢失的ATM通信网络拥塞控制方法·实验结果表明 ,该方法硬件实现简单并能动态分配带宽、充分利用网络资源、及时解除网络拥塞 ,尤其采用了共享缓存器 ,信元的丢失率趋于零·A lossless congestion control method for ATM communication networks was proposed. The control model is based on rate control with credit control and used on one VC link to realize per VC congestion control. It makes cell drop ratio very small since share buffers are applied on every node in network. The method was simulated on an experimental system, its performance was analyzed, and compared with leaky bucket control method. The model can allocate bandwidth dynamically, utilize resource effectively, eliminate congestion on time and reduce complexity and cost.
