Course Overview
Hi, everyone. My name is Chris Greer, and welcome to my course, Troubleshooting Slow Networks with Wireshark. I'm a network analyst at Packet Pioneer and have been teaching protocol analysis with Wireshark for nearly 20 years. Now, slow networks are very frustrating to end users, network engineers, and application support people. And let's face it, the network usually gets the blame even when we know it's not the network. Capturing and interpreting packets with Wireshark can give us the detail we need to quickly isolate the problem to the client, network, or server and point to the real root cause. Now, Wireshark can be overwhelming when we're just getting comfortable with protocols and how to interpret them. However, in this course, we're going to use hands‑on demonstrations with shared trace files to help you learn more than just how to capture, but how to practically interpret packets and resolve network problems. So, get your copy of Wireshark ready and follow along as we discuss capturing the right packets in the right places at the right time, measuring network latency and packet loss, measuring application response time, and creating custom filters and columns for pinpointing problems, and much, much more. By the end of this course, you'll be able to use Wireshark to identify and resolve many common problems in networks that cause slowness. Before beginning the course, you should be familiar with IT networking, in general, and you may have already taken the course on Getting Started with Analyzing Network Traffic Using Wireshark, although this is optional. From here, you should feel comfortable moving on to other courses in the Wireshark learning path. I hope you'll join me on this journey to learn network and application troubleshooting with the Troubleshooting Slow Networks with Wireshark course, here at Pluralsight.
