每发出一个报文段，TCP就设定一个定时器并等待确认信息。
Once sending a segment, TCP sets a timer and waits for the ACK.
幸运的是，OStcp层可以负责将协议数据划分为避免IP分片的tcp报文段。
The OS TCP layer fortunately takes care of splitting the protocol data into TCP segments that avoid IP fragmentation.
为了克服由大时延带来的重传时间间隔过大的缺点，采用了批量重传来及时重传丢失的报文段；
In order to alleviate the long retransmission intervals brought by long propagation delays, bulk retransmissions are introduced to retransmit the lost packets in time.
文中介绍了TCP报文的封装情况、TCP报文段格式规定和TCP连接中的“三次握手”协议。
The specification of TCP as well as its three way handshake is introduced in the paper.
使用这种方法，您至少可以了解(或者猜测)在不对ip层进行分片的情况下可能通过的tcp报文段的大小。
Using this method, you can at least know (or guess, rather) what TCP segment sizes are likely to be passed through without getting fragmented at the IP level.
如果在报文段中的数据未确认之前定时器超时，TCP就认为该报文段已经丢失或出现损坏，从而重传这一报文段。
If the timer expires before data in the segment is acknowledged, TCP assumes that the segment has lost or being damaged, and a retransmission is sent.
