TCP可靠数据传输 在TCP在IP不可靠的尽力而为的服务之上,创建了一条可靠数据传输服务(reliable data transfer service)。 TCP提供的可靠数据传输的方法涉及到可靠数据传输原理中许多机制。 也涉及到了定时器。如果为每一个已发送但未被确认的报文段都设置一个定时器,那开销是相当巨大的。因此 推荐的定...
connection establishment data transfer [2] connection release [2] Global sequence number and subflow sequence number 因为两个路径通常具有不同的延迟特性,所以将不会按顺序接收通过两个子流发送的数据段。常规TCP使用每个TCP数据包报头中的序列号将数据放回原始顺序。一个简单的多路径TCP解决方案是按原样重用此序...

flow. However, it has also been found that in the network wherethe propagation delay is large, the goodput of the end-to-end TCP flow improves. We have shown thatusing the SACK option solves the problem of the decreased goodputof the end-to-end TCP flow. We have also shown that when...
This data flow looks a little different than the previous one when it comes to data acknowledgement. Near the end of the data flow we can see the server sending out 3 ACKs in a row with the same ACK number 17521. This pattern is known as the request...
If possible, avoid socket connections with unidirectional data flow. Communications over unidirectional sockets are more easily impacted by the Nagle and delayed acknowledgment algorithms. If the communication follows a request and a response flow, you should use a single socket to do both sends and ...
Together, the two variables are used to regulate data flow in TCP connections, minimize congestion, and improve network performance. 笔者在rfc5681文档中也看到cwnd的定义: 这个解释指出了cwnd是在发送方维护的,cwnd和rwnd并不冲突,发送方需要结合rwnd和cwnd两个变量来发送数据,如图所示: cwnd的大小和MSS最大...
