我对 RTT 有疑问。我想知道 RTT 是否相关,以及它与拥塞情况下的带宽分配有何关系(如果相关)
答案1
对于使用拥塞控制的协议(如 TCP),RTT 应该会影响拥塞控制算法。
在第二个链接中,您可以阅读(来自“TCP Tahoe 和 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).
