我对RTT有疑问。 我想知道RTT是否相关,以及在拥塞情况下如何(如果是)与带宽分配有关
看看这两个页面: link1和link2从维基百科。
在使用TCP等拥塞控制协议的情况下,RTT应该会影响拥塞控制algorithm。
在第二个链接中,您可以阅读(从“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).
