我正在复习网络考试,我不确定以下问题的答案:

Consider the effect of using slow-start on a link with a 10ms round-trip time
and no congestion. The receive window is 24KB and the maximum segment
size is 2KB. How long does it take before the first full window can be sent
in one transmission round?

每次确认后,最大段大小是增加1还是增加一倍?如果它加倍,答案会是50ms吗?因为2KB^5=32KB,所以在5次行程后,MSS将等于32KB,而由于10ms的往返时间,答案会是10x5=50ms?

我在这里找到了问题4的解决方案:

您或多或少都是正确的,只是忽略了最后一个RTT,因为窗口大小超过了24KB。所以你的答案是:

4 x 10=40毫秒
