The author of the cURL utility Daniel Stenberg told about the approval of the decision to promote the HTTP-over-QUIC protocol as the future standard HTTP / 3. This is done by the Internet Engineering Council (IETF).
It has been developing Google since 2013 as an alternative to TCP + TLS. The main advantage is to reduce delays in packet loss and reduce installation time and reconciliation of connections. Technically, QUIC is a superstructure over UDP. QUIC supports multiplexing of multiple connections, as well as encryption methods similar to TLS / SSL.
The protocol is already used in the company, embedded in its client-server infrastructure and is part of Chrome. It is also planned to be included in Firefox.
The new protocol is supported by Cloudflare and Verizon Digital Media Services, testing is conducted by Apple, Pandora and Facebook. Also, more and more sites are moving to a new standard. However, while the technology remains experimental, and the timing of its release in the release is not specified.
In June 2018, Google talked about using the QUIC protocol to balance network loads when transmitting data using HTTPS.
