How 3-way Handshake is used in Wireshark?
Ans: 3-way handshake is a well-known method required in TCP/IP network for establishing
proper connection in between two that is client and server. It comprises of three steps which
require both client and server for proper exchange synchronization. This aims in acknowledging
the packet before the data communication process begins (Cunha et al. 2016). The process has
been designed in such a way that both the sides help in initiate, negotiate and differentiate TCP
socket connections. This merely helps in proper transfer many TCP socket connections in two
direction at the same instance.
TCP traffic generally begins by the help of a three-way handshake. In this particular TCP
process, client need to start the conversation by establishing communication session with server
(Oliveira et al. 2017). Different kind of TCP messages are explained below:
Messages Description
Syn Required for initiation and establishing
connection.
ACK Helps in assuring that other side has received
SYN.
SYN-ACK SYN messages from the local server and
ACK of earlier package.
FIN Required for terminating a connection.
Step 1: In this step, client aims in establishing connection with server where it provides a
segment with SYN followed by informing server about client details.
