Standard HTTP\/3 ur\u010duje pou\u017eit\u00ed protokolu QUIC (Quick UDP Internet Connections) jako transportn\u00edho prost\u0159edku pro HTTP\/2.

V nghttp3 je poskytov\u00e1na nez\u00e1visl\u00e1 implementace specifikac\u00ed RFC 9114 (HTTP\/3 nad protokolem QUIC), RFC 920 (technologie komprese hlavi\u010dek QPACK), RFC 9220 (p\u0159ed\u00e1v\u00e1n\u00ed WebSocket\u016f nad HTTP\/3) a RFC 9218 (roz\u0161i\u0159iteln\u00fd sch\u00e9ma pro \u0159\u00edzen\u00ed priorit p\u0159i odes\u00edl\u00e1n\u00ed odpov\u011bd\u00ed na po\u017eadavky klienta).
