The New Encrypted Protocol Stack: Understanding QUIC, HTTP/3, and Modern Network Traffic - Session 4760

Learn about the rapid transition from TCP to QUIC protocols in this 48-minute NANOG conference talk that explores the revolutionary changes in network traffic protocols. Dive deep into how QUIC, already accounting for nearly 50% of total traffic, works alongside HTTP/3, DNS over HTTP (DoH), and eSNI/ECH over TLS 1.3 to create a fully encrypted protocol stack. Understand the challenges this evolution presents for traditional TCP/IP technologies and L4+ monitoring techniques, as applications gain unprecedented control over end-user delivery. Explore real-world traffic analysis across mobile and fixed networks, examine the impact on infrastructure elements including Radio Access Network (RAN), and discover practical techniques for communication service providers to adapt their network architecture. Master the concepts of traffic visibility, Quality of Experience optimization, and efficient 5G spectrum utilization while learning how to navigate the complexities of modern network protocol stacks.
