Network Analysis Using Wireshark 2 Cookbook - Second Edition
by Nagendra Kumar Nainar, Yoram Orzach, Yogesh Ramdoss
Introduction
In this chapter, we will primarily focus on the transport layer of the OSI reference model and learn how to analyze various layer 4 protocol (TCP/UDP/SCTP) operations. The transport layer protocol is a host-to-host communication protocol that is responsible for data exchange between end applications running on different hosts. The User Datagram Protocol (UDP) is a simple connectionless protocol that simply delivers the datagram to the intended recipient without any reliability mechanism. On the other hand, Transport Control Protocol (TCP) is a connection-oriented protocol and its primary purpose is to provide reliable, congestion-aware data delivery between end applications.
