一种新的互连网络拥挤控制

A NEW CONGESTION CONTROL POLICY FOR THE INTERNETWORKS

本文详细讨论了互连网络拥挤控制;指出了一般网络内拥挤控制方法不能成功地应用于互连网络的原因。首次提出了一种新的互连网络的拥挤控制方法,它视互连网络为一黑匣,完全利用互连设备——网间连接器(Gateway)的功能进行拥挤控制。计算和模拟分析验证了该方法的突出特性,并与R。Jain(1986)提出的拥挤控制法进行了比较。

This paper discusses the distinction between internetworks and single network in the congestion control. It has shown the reason why all of single network's congestion controls are not suitable to internetworks. A new congestion control scheme for internetworks is presented which uses the acknowledgments of the timeouts and the feedback signal from the gateway as the indications of packet loss and congestion. Using a black-box model of the internetworks, the author derives several approximate calculating formulas and proves the scheme's special characters by computer simulation. It is shown that the presented method is better than R. Jain's method (1986).
