IETF publishes QUIC as RFC 9000

by ·

Internet Engineering Task Force (IETF ) has published QUIC as RFC 9000 and is supported by RFC 9001, RFC 9002, and RFC 8999. This means that the first version of QUIC has been officially finalized, and the version used to deploy QUIC has also been changed from a temporary draft version to a new first version (HTTP/3 as HTTP running on QUIC will also be released soon).
The RFC Editor page shows that RFC 9000 is currently in the “PROPOSED STANDARD” status and has not yet become an official standard.
HTTP/3
Quick UDP Internet Connections (QUIC) is a new generation of Internet transmission protocol that reduces latency, is reliable and secure, and is considered to replace the most commonly used transmission protocol TCP today.

QUIC was originally designed by Jim Roskind of Google, implemented and deployed in 2012, and was publicly released in 2013 as the scope of the experiment expanded and described to IETF. In June 2015, the Internet draft of the QUIC specification was submitted to the IETF for standardization. In 2016, the QUIC working group was established. In October 2018, the IETF HTTP working group and the QUIC working group jointly decided to call the HTTP mapping on QUIC “HTTP/3” in order to make it a global standard in advance.

QUIC aims to provide reliability almost equivalent to TCP connection, but with greatly reduced latency. One of the reasons is that it greatly reduces overhead during connection creation. QUIC uses the UDP protocol as its basis and does not include loss recovery.
