2. Flow Control Flow control limits the rate at which a sender transfers data. This is done to ensure reliable delivery. The receiver continually hints the sender on how much data can be received (using a slidin
Flow Control is all about making sure we don’t send more packets when the receive buffer is already full, as the receiver wouldn’t be able to handle them and would need to drop these packets. To control the amount of data thatTCPcan send, the receiver will advertise itsReceive Window ...

net->ipv4.tcp_congestion_control = init_net.ipv4.tcp_congestion_control; else net->ipv4.tcp_congestion_control = &tcp_reno; 如果有指定拥塞控制的,则调用指定的拥塞控制模块。默认是RENO算法。在Debian系统上默认是CUBIC拥塞控制算法。注册结构体为cubictcp。
2. Flow control using sliding window(包括Nagle 算法等,批量传) 3. Congestion control(包括slow start、congestion avoidance、fast retransmit等) 第一点已经足以满足“可靠性”要求(为什么?); 第二点是为了提高吞吐量,充分利用链路层带宽; 第三点是防止过载造成丢包。

Flow control.TCP managesflow controlby managing the rate of data transmission between the sender and the receiver. Flow control ensures the receiver isn't flooded with data it can't handle promptly. Error handling.TCP handles retransmission of dropped or garbled packets, as it's meant to provide...
