我刚刚运行了一个模拟多路径tcp协议,在网络模拟器3中从客户端向服务器发送100,000个字节。我得到了跟踪文件(pcap)并在Wire Shark中对其进行了分析。 flow graph非常奇怪。如何在双方发送和接收ACK?
答案 0 :(得分:0)
如何在双方发送和接收ACK?
因为这就是TCP的工作原理。 RFC 793说:
Acknowledgment Number: 32 bits
If the ACK control bit is set this field contains the value of the
next sequence number the sender of the segment is expecting to
receive. Once a connection is established this is always sent.
因此,一旦建立连接,连接中的每个数据包都设置了ACK位。
