Udemy – Transmission Control Protocol (TCP) from Scratch!! 2023-7 – Download

Description

Transmission Control Protocol (TCP) course from scratch. TCP protocol is one of the most overlooked concepts for a network engineer. This is one of the most important protocols that every network engineer must understand to do their job effectively. Many people fail the interview if they don’t have a complete picture of TCP. This is one of the most detailed video courses ever made on TCP protocol. We will have very simple examples from our daily life to talk about each aspect of TCP protocol. Let’s learn Layer 4 in detail. We will cover the following topics in this course.

Connection establishment: see sequence number, acknowledgement, sector, TCP headers and flags, TCP 3-way handshake and everything in Wireshark
Flow control: buffering, data transfer, windowing, opening and closing windows, separation, silly window syndrome, Nagel’s algorithm. A few examples.
Error control: confirmation, duplicate ACs, confirmation rules, checksum, our parts of the order, re-send. Some scenarios
Congestion control, timers and options: slow TCP start, Windows congestion, congestion policy, RTO, persistent timer, selective acknowledgements
Let’s put all the puzzles together and create our own TCP header. Believe me, you don’t need to memorize any field of the TCP header because at this point you will understand the why behind each field. You can create the TCP header from scratch.
