Mastering TCP Analysis with Wireshark

by Chris Greer

A deep level understanding of the transport control protocol is critical for any network engineer in solving network and application performance problems. This hands on course will help you heighten your expertise of TCP.

What you'll learn

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

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.
