根据无线ATM网的特征 ,提出一种分段式、无须改变骨干 (有线 )网络中流控算法的ABR业务组播连接流控算法 ,经过数值模拟分析 ,结果表明我们提出的算法既可以在空中接口使接收机吞吐量得以充分利用 ,又可以保持骨干 (有线 )网中带宽资源的有效利用 According to the characteristics of wireless ATM network, this paper proposes a segmented ABR service multicast connection flow control algorithm without changing the flow control algorithm in the backbone (wired) network. After numerical simulation, the results show that the proposed algorithm can be implemented either over the air interface So that the receiver can take full advantage of throughput, but also to maintain the effective use of backbone bandwidth (wired) network resources
