10 Issue 2.3 ibaPDA-Interface-S7-TCP/UDP 3.2.1.1 Header The header consists of 3 integer values. Data interface TCP/UDP to SIMATIC S7 ■ Message_length Total size (in bytes) of the data packet. This value must not be changed during data transmis- sion. This value also has to be ...
(1) 应用程序发送的根据网络环境切割成合适大小的数据段(Segment)。如果接收方发现数据有误,只需要丢弃一个数据段的数据,降低重传成本。 (2)通过 TCP 协议发送数据之后,会等待对端发送确认信息(ACK),以保证对端已正确接收数据。 (3)TCP 协议维护有重传计时器(retransmission timer),指定时间内没有收到对端的确认...
3 way Handshake Diagram Step 1:In the first step, the client establishes a connection with a server. It sends a segment with SYN and informs the server about the client should start communication, and with what should be its sequence number. ...
TCP handshake waved schematic diagram: TCP window control and retransmission control In the use of window control, if there is a segment loss, first consider the situation that the confirmation response fails to return. In this case, the data has arrived at the opposite end, and there is...

A TCP sender computes a value based on the contents of the TCP header and data fields. This 16-bit value will be compared with the value the receiver generates using the same computation. If the values match, the receiver can be very confident that the segment arrived intact. ...

因为有部分segment正在路上,还没有收到receiver的ackno,所以应该假设这部分segment可以顺利到达,给他们提前留出空间,所以判断逻辑应该是:window_size > bytes_in_flight(),另外,min(TCPConfig::MAX_PAYLOAD_SIZE, window_size - bytes_in_flight())也是我们下一次应该发送的字节数~...
