QUIC

Noun · Development

Definitions

  1. A transport protocol built on UDP that provides the reliability of TCP with faster connection setup, built-in encryption (TLS 1.3), and multiplexed streams without head-of-line blocking. QUIC is the foundation of HTTP/3.

    In plain English: A faster, more modern replacement for TCP that reduces connection delays and handles packet loss more gracefully.

    Example: "Switching to HTTP/3 with QUIC shaved 200ms off our time-to-first-byte for mobile users on flaky connections."
