比较研究了一种特殊信源——Ｓｏｕｒｃｅ－ｂｏｔｔｌｅｎｅｃｋ 信源在ＡＴＭ 网络中对ＡＢＲ拥塞控制算法性能的影响．Ｓｏｕｒｃｅ－ｂｏｔｔｌｅｎｅｃｋ 信源由于某些原因无法做到根据交换网络提供的信息相应改变信元发送速率， 由于网络交换节点对此不了解必然导致对Ｓｏｕｒｃｅ－ｂｏｔｔｌｅｎｅｃｋ 信源分配的速率过大而浪费网络资源．当Ｓｏｕｒｃｅ－ｂｏｔｔｌｅｎｅｃｋ 信源不再发生信源拥塞情况时， 网络又会因为瞬间增加的速率而发生拥塞．本文对不同的ＡＢＲ拥塞控制算法进行了仿真， 并对结果进行了分析
The effect of Source-bottleneck source on the performance of ABR congestion control algorithm in ATM network is comparatively studied. Source-bottleneck source can not change the cell sending rate according to the information provided by the switching network for some reason, which istes the network resources because the network switching node does not understand the inevitable result of the rate of source-bottleneck source allocation being too large . When source-bottleneck sources no longer experience congestion, the network is congested again due to an instantaneous rate of increase. In this paper, different ABR congestion control algorithms are simulated and the results are analyzed
