Analyzing TCP connections is one of the biggest topics in network analysis in general, especially when troubleshooting applications or even multi-tiered deployments of servers. How TCP works and detecting problems is one of the 'easy to learn, hard to master' skills that is always in demand. Most Wireshark classes only touch the basics and do not go into the more complex scenarios, especially when it comes to multi point captures to track packet loss and timing issues. In this masterclass you will learn how to troubleshoot TCP in seemingly simple as well as complex and quite challenging cases.
