Understanding QUIC: Transport‑Layer Implementation of HTTP/3 and Its Key Features

QUIC, a UDP‑based transport protocol that merges TCP reliability, UDP speed, and TLS security, underpins HTTP/3 by eliminating TCP’s three‑way handshake and head‑of‑line blocking, offering connection migration, 0‑RTT latency, customizable congestion control, fully encrypted packets, and is already being deployed in services such as Tencent Cloud CDN.
