ACK
and SYN
segment names
refer to "control bits" in the TCP header: for example, if the
ACK
bit is set, then this is an
ACK
segment.x
and
y
in this example). This is crucial to the
protocol's operation if there's a small chance that "old" segments
(from a closed connection) might be interpreted as valid within the
current connection.Lecture 11: Reliable Transport -- TCP | Copyright © 2005 P.Scott, La Trobe University Bendigo. |
