linux关于tcp协议ack的实现--发送端对ack的处理

前面的文章分析了接收端如何发送ack给发送端，总结一下就是立即ack，捎带ack和延迟ack，现在看一下tcp的发送端是如何处理ack的，本质上tcp所谓的有连接就是双方对于seq和ack的处理，对于seq，发送方是主动的，而接收端是被动的，但是对于ack则相反，因此参照tcp的流控以及拥塞控制加之...

linux关于tcp协议ack以及乱序报文暂存的实现--立即ack/延迟ack/捎带ack

tcp需要ack，可是为了效率，并不是每发送一个数据都要等待ack，而是尽可能利用窗口机制，积累发送ack的，当然在某些特殊情况下还是需要马上发送ack的，比如接收到乱序的数据，这种情况下，虽然接收端可以将乱序的数据包暂存，但是接收方必须发送一个ack号为按序的期望的序列号的ack给发送端，另外就是...

linux关于tcp协议ack的实现--总结和公平性问题

tcp是一个可靠连接的协议，但不要指望它是什么理论的实现，它是实践的东西，任何实践的东西背后都不是一个理论，而是一大堆理论，tcp正是单一停等，GBN(回退N)以及SR(选择重传)的结合体，单一停等是最原始的理论，但是带宽利用率太低了，后面的GBN实现了流水线式的数据发送和确认，可靠连接的根本就在于...

Linux有问必答：如何使用tcpdump来捕获TCP SYN，ACK和FIN包

Linux有问必答：如何使用tcpdump来捕获TCP SYN，ACK和FIN包问题：我想要监控TCP连接活动（如，建立连接的三次握手，以及断开连接的四次握手）。要完成此事，我只需要捕获TCP控制包，如SYN，ACK或FIN标记相关的包。我怎样使用tcpdump来仅仅捕获TCP SYN，ACK和/...
