RTT和带宽分配

Question

我对RTT有疑问。我想知道RTT是否相关，如果是的话，它与拥塞情况下的带宽分配有什么关系？

Answer 1

看看这两页:维基百科的link1和link2。

对于使用TCP等拥塞控制的协议，RTT应影响拥塞控制算法。

在第二个链接中，您可以阅读(来自"TCP Tahoe and Reno“部分)：

It starts with a window of two times the maximum segment size (MSS).
Although the initial rate is low, the rate of increase is very rapid: for every packet acknowledged,
the congestion window increases by 1 MSS so that the congestion window effectively doubles for every round trip time (RTT).
