TCP Connection Management:<br />
2. Data Transmission<br />
Client Server ● Full-duplex connection<br />
● Segmentation of a byte stream into<br />
segments.<br />
● Usual sizes are 1500, 536, or 512<br />
byte; thus IP fragmentation is<br />
avoided.<br />
● All hosts have to accept TCP<br />
segments of<br />
536 byte +20 byte = 556 byte<br />
● Usual acknowledgement mechanism:<br />
● All segments up to ACK-1 are<br />
confirmed. If the sender has a<br />
timeout before an ACK, he repeats<br />
the sending.<br />
● Usual procedure for repeating:<br />
● Go-Back-N or Selective Repeat<br />
