Description

The network is slow! People still say it. In this course, Mastering TCP Analysis with Wireshark, you will gain the ability to quickly identify and isolate network problems, whether TCP is the root cause or not. First, you will learn how TCP recovers from a lossy network. Next, you will discover how the often-confusing TCP congestion control mechanism works. Finally, you will explore how to visualize TCP flows to quickly hone in on problem spots. When you are finished with this course, you will have the skills and knowledge of TCP needed to isolate and resolve network and application performance issues.

Course FAQ
Course FAQ
What is TCP?

Transmission Control Protocol (TCP), is a bridge between the network and the application traffic that traverses it. With a thorough understanding of TCP, engineers can quickly pinpoint and resolve issues that plague performance, rather than guessing at a solution and hoping for the best.

Why use Wireshark?

Wireshark is a free network traffic analyzer tool that network adminstrators and engineers can use to troubleshoot and analyze network and security problems.

What will I learn in this course?

This Wireshark course will help you learn how to quickly identify network problems. You wil learn major topics such as;

  • TCP SACK and packet loss recovery 
  • Congestion control algorithms
  • And graphing TCP streams in Wireshark.
Are there prerequisites to this course?

This is an advanced level course that expects users to have an understanding of TCP and an intermediate level understanding of TCP analysis with Wireshark.

Course Overview
Hi, everyone. My name is Chris Greer, and welcome to my course, Mastering TCP Analysis with Wireshark. I'm a network analyst at Packet Pioneer, and I've been using Wireshark to troubleshoot pesky network problems for over 15 years. I'm excited for the opportunity to teach you more about TCP and how to analyze it with Wireshark. After all, TCP is a bridge between the network and the application traffic that traverses it, but few in the IT organization have a solid grasp of how it really works. With a thorough understanding of TCP, engineers can quickly pinpoint and resolve issues that plague performance, rather than guessing at a solution and hoping for the best. In this hands‑on, exercise‑driven course, we're going to go beyond the basics of the TCP protocol and dive deep into its function and behavior. Some of the major topics that we'll cover include TCP SACK and packet loss recovery, congestion control algorithms, and graphing TCP streams in Wireshark. By the end of this course, you'll have a skilled understanding of how to analyze TCP to resolve network problems for good. Before beginning the course, you should be familiar with the basics of how TCP works. You should have already viewed the course, Foundational TCP Analysis with Wireshark, or have an intermediate understanding of the protocol. I hope you'll join me on this journey to examine TCP with the course, Mastering TCP Analysis with Wireshark here on Pluralsight.
