HTTP-over-QUIC to be renamed HTTP/3

The HTTP-over-QUIC experimental protocol will be renamed to HTTP/3 and is expected to become the third official version of the HTTP protocol, officials at the Internet Engineering Task Force (IETF) have revealed.

This will become the second Google-developed experimental technology to become an official HTTP protocol upgrade after Google’s SPDY technology became the base of HTTP/2.

HTTP-over-QUIC is a rewrite of the HTTP protocol that uses Google’s QUIC instead of TCP (Transmission Control Protocol) as its base technology.

QUIC stands for “Quick UDP Internet Connections” and is, itself, Google’s attempt at rewriting the TCP protocol as an improved technology that combines HTTP/2, TCP, UDP, and TLS (for encryption), among many other things.

Google wants QUIC to slowly replace both TCP and UDP as the new protocol of choice for moving binary data across the Internet, and for good reasons, as test have proven that QUIC is both faster and more secure because of its encrypted-by-default implementation (current HTTP-over-QUIC protocol draft uses the newly released TLS 1.3 protocol).

QUIC was proposed as a draft standard at the IETF in 2015, and HTTP-over-QUIC, a re-write of HTTP on top of QUIC instead of TCP, was proposed a year later, in July 2016.

Since then, HTTP-over-QUIC support was added inside Chrome 29 and Opera 16, but also in LiteSpeed web servers. While initially, only Google’s servers supported HTTP-over-QUIC connections, this year, Facebook also started adopting the technology.

In a mailing list discussion last month, Mark Nottingham, Chair of the IETF HTTP and QUIC Working Group, made the official request to rename HTTP-over-QUIC as HTTP/3, and pass it’s development from the QUIC Working Group to the HTTP Working Group.

In the subsequent discussions that followed and stretched over several days, Nottingham’s proposal was accepted by fellow IETF members, who gave their official seal of approval that HTTP-over-QUIC become HTTP/3, the next major iteration of the HTTP protocol, the technology that underpins today’s World Wide Web.

According to web statistics portal W3Techs, as of November 2018, 31.2 percent of the top 10 million websites support HTTP/2, while only 1.2 percent support QUIC.
