基于UDP的可靠性传输协议-KCP简介

RTO翻倍vs不翻倍：TCP超时计算是RTOx2，这样连续丢三次包就变成RTOx8了，十分恐怖，而KCP启动快速模式后不x2，只是x1 .5（实验证明1 .5这个值相对⽐较好），提高了传输速度。if (kcp->nodelay == 0) { segment->rto += _imax_(segment->rto, (IUINT32)kcp->rx_rto); } e...

2.6 TCP与UDP的可靠性传输

一、TCP可靠性传输参考小林图解网络1、重传机制1.1、超时重传超时重传，就是在发送数据时，设定一个定时器，当超过指定的时间后，没有收到对方的 ACK 确认应答报文，就会重发该数据。TCP 会在以下两种情况发生超时重传：数据包丢失确认应答丢失超时重传时间 RTO是一个动态变化的值，其值应该略大于报文往返 RTT 的值。RFC6298建议使用下式计算超市重传时间RTO：即出现超时重传时，新的RTO....
