HTTP/3 and QUIC position in the protocol stack

QUIC convention focuses on straightforwardness and speed.

As per Google, QUIC handshakes habitually require zero roundtrips before sending payload, when contrasted with 1–3 roundtrips for TCP+TLS.

All things considered, the main association ever requires one roundtrip and the followings will work with zero.

Right now, just 1.2 % of the top sites support QUIC, however they are commonly high-traffic locales. Every Google service underpins their own QUIC convention.


QUIC first advancement incorporated its own encryption. Be that as it may, it was only an impermanent usage bound to be supplanted by TLS 1.3 as depicted by the IETF.

In reality, the association foundation technique of QUIC depends on the mix of crypto and transport handshake.
