摘　　要：运用现代控制理论和方法,在多个信源节点单个信终端节点的端对端模型基础上,考虑到信终端节点的缓冲占有量的动态稳定,设计了一类可以比较好地调节ABR信源节点发送速率的控制器,使得终端节点的缓冲占有量可以逐渐稳定。The present paper proposes a novel control theoretic approach that designs a class of controllers for congestion regulation. Based on the traffic model with multiple source nodes and a single destination node,i.e.,the so-called end-to-end model and on system stability criterion,it is shown that the controllers can regulate the source rates on the basis of the knowledge of buffer occupancy of the destination node such that the network is asymptotic stable in terms of the buffer occupancy of the destination node.

关 键 词：计算机通信网络 拥塞控制 缓冲占有量 稳定性
