UDP does not use the three-way handshake. Internet LayerAs shown in Figure 2–1, both TCP and UDP pass their segments and packets down to the Internet layer, where the IP protocol handles the segments and packets. IP prepares them for delivery by formatting them into units called IP ...
One of the ways in which TCP ensures reliability is through the handshake process. Establishing a TCP session would begin with a three-way handshake, followed by data transfer, and then a four-way closure. The four-way closure where both sender and receiver agree on closing the s...
A TCP connection is initialized through a three-way handshake. The purpose of the three-way handshake is to synchronize the sequence number and acknowledgment numbers of both sides of the connection and exchange TCP window sizes or the use of large window sizes or TCP timestamps. The following...
When TCP time stamp is used in a TCP session, the originator of the session sends the option in its first packet of the TCP three-way handshake (SYN packet). Either side can then use the TCP option during the session.TCP Timestamps Option (TSopt):...
