The Road to QUIC

What this post added

This post introduces QUIC (Quick UDP Internet Connections) as a new encrypted-by-default Internet transport protocol designed to replace TCP and TLS. It details QUIC's key features, including built-in security and performance improvements through combined handshakes, encryption of metadata to combat ossification, and independent stream delivery to mitigate head-of-line blocking. The post also highlights the challenges in supporting QUIC, such as NAT rebinding and connection migration issues, and introduces connection IDs as a solution. It also touches upon QPACK for header compression in the context of QUIC's independent stream delivery.
