TCP has reliably delivered applications and services for over 40 years. Now, it has a "QUIC" competitor. In this course, Protocol Deep Dive: QUIC, you’ll gain the ability to understand, test and troubleshoot this new protocol. First, you’ll explore why a TCP replacement was needed. Next, you’ll discover how QUIC secures and transports traffic. Finally, you’ll learn how to test and validate networks and servers for QUIC support. When you’re finished with this course, you’ll have the skills and knowledge of the protocol needed to analyze and troubleshoot QUIC-based applications.

Course Overview
Hi, everyone. My name is Chris Greer, and welcome to my course, Protocol Deep Dive; The QUIC Protocol. I'm a network analyst and Wireshark instructor at Packet Pioneer, and I'm excited to dig into this rapidly emerging protocol with you. Now, TCP has been the dominant transport protocol under the hood of most applications and services for over 40 years, but now it has a competitor. First invented at Google and now in the hands of the IETF, QUIC is already being used today to deliver many of the web services that we know and love. Now, a lot of this has happened under our noses over the past few years. But with QUIC becoming a standard, we will soon see it deployed all over the internet to deliver web and mobile applications to end users. This course will cover the key concepts about QUIC that every network engineer, developer, and cybersecurity professional should know. Some of the major topics that we'll cover include the core differences between TCP and QUIC, why a new transport protocol was needed, how QUIC securely and reliably transports data, and we'll look into some tools for testing and validating QUIC. By the end of this course, you will understand how to analyze, validate, and troubleshoot the QUIC protocol. Before beginning the course, you should be familiar with basic networking concepts and the Wireshark analyzer. I hope you'll join me on this journey to learn QUIC, the new competitor to TCP, with this Protocol Deep Dive, course here, at Pluralsight.
