Transport Layer

Protocols used: TCP (connection-oriented), UDP (connectionless)

[m5-2]

How three-way handshake work?

The source (client) sends an SYN packet to the destination system (server/host)
The destination system replies with an SY packet & acknowledges the source system’s SYN packet by sending an ACK packet.
The source system sends an ACK packet to acknowledge the SYN/ACK packet sent by the host.

Thus the connection is established between the source system and host.
