Description

TCP is a core protocol driving business applications, but is often a blind spot in IT organizations. A thorough understanding of TCP can speed up network and application troubleshooting, empowering engineers to quickly resolve problems.

What You'll Learn?

"The network is slow!" "The application is broken!" "We are being hacked!" Sound familiar? In this course, Foundational TCP Analysis with Wireshark, you will gain the ability to troubleshoot and resolve network problems by harnessing the power of TCP. First, you will learn how TCP connections are established and maintained. Next, you will discover how data is retransmitted during data loss. Finally, you will explore how to quickly find, interpret, and resolve TCP problems using the Wireshark protocol analyzer. When you are finished with this course, you will have the skills and knowledge of the TCP protocol and Wireshark needed to hunt down network problems and resolve them for good.
