How TCP works | TCP Header | Source Port | Destination Port | Window | SYN | FIN | PSH | URG | RST

In this video, we will explore the TCP header, which is a fundamental part of the Transmission Control Protocol (TCP), used for transmitting data over the internet. Understanding the structure and content of the TCP header is essential for network engineers, security professionals, and anyone working with network traffic analysis.
Video concepts:
Tcp encapsulation
Source Port
Destination Port
Sequence Number
Acknowledgement number
Header Length
TCP flags
SYN flag
FIN flag
PSH flag
URG flag
RST flag
Window Size
TCP Checksum
We will begin by explaining the purpose and function of the TCP header, and its role in establishing and maintaining reliable connections between network devices. We will then dive into the anatomy of the TCP header, covering each field and its significance in the packet transmission process.
We will explore key concepts such as the source and destination ports, sequence and acknowledgement numbers, and window size, and how these fields are used to manage data transmission and ensure packet integrity. We will also cover the flags used in the TCP header, including the SYN, ACK, FIN, and RST flags, and their role in establishing and terminating connections.
Throughout the video, we will provide real-world examples of TCP packet analysis and demonstrate how to interpret the contents of a TCP header using packet capture tools such as Wireshark.
By the end of this video, you will have a solid understanding of the TCP header and its importance in the world of network traffic analysis. Whether you are an experienced network engineer or just starting in the field, this video is a must-watch for anyone looking to enhance their knowledge of TCP packet transmission.
