QUIC

Published At: June 3, 2026

QUIC is a general-purpose transport protocol developed by Google and later standardized by the IETF. It runs over UDP rather than TCP, while still providing reliable, ordered delivery, built-in encryption, and multiplexed streams. Unlike TCP, where a lost packet stalls the entire connection, QUIC isolates packet loss to the individual stream it affects. QUIC is the transport layer that powers HTTP/3, and serves as the foundation for newer media protocols like Media over QUIC (MoQ).
