It has shown the reason why all of single network’s congestion control is not suitable to internetworks. A new congestion control scheme of internetworks is presented which uses acknowledgment time-outs and the feedback signal from gateway as indications of packet loss and congestion. Using a black-box model of the internetworks, this paper derives 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 (1986).展开更多
