You enable lower granularity for the retransmission timer for this connection and resend the packet. 您为这个连接启用了更低粒度的重新传输计时器,并重新发送数据包。
TCP uses a retransmission strategy to insure that data will not be lost in transmission. 传输控制协议利用再传输策略保证数据不会在传送中丢失。
Lossless protocols require retransmission of lost packets, which substantially increases transmission time. 无损协议对待丢失的数据包要求重传(RTNS),这大大增加了传输时间。
This allows the receiving node to validate its incoming data and request retransmission when an error is found. 这支持接收节点验证输入数据,并在发现一个错误时请求重发数据。
This article explains an alternative method for implementing TCP's retransmission timer based on a timer wheel algorithm. 本文说明了基于计时器轮算法实现TCP的重新传输计时器的一种备选方法。
