And in the link layer a router buffer queue managing mechanism is set to compute the network congestion probability and then feedback it to the sender. It can also differentiate the packet losses between congestion and link error to avoid reducing the send window unnecessarily.
协议根据链路层反馈的有效带宽信息准确地设定拥塞窗口门限阈值;在网络层对路由器缓冲队列进行管理,计算网络发生拥塞的概率并发送显示拥塞通知反馈给发送方传输层;还可区分丢包原因,避免由于传输错误造成的发送窗口减小。
