Hi everyone,
Here is a quick status update on Chrome's QUIC plans.
1) Q050
Q050 is now the default version, and is responsible for
the majority of QUIC traffic from Chrome. As a reminder,
a guide for parsing that version (and others) is available
2) Older GoogleQUIC versions
Q048 and Q049 have now been fully removed. There
is still some amount of traffic using Q043 and Q046,
though we expect that to reduce over time, and we'll
remove them once traffic is low enough.
3) New GoogleQUIC versions
We are currently experimenting with T050 and T051.
These versions are very similar to Q050, but use TLS
as their handshake protocol. Our current plan is to
keep experimenting with these for roughly 1% of
users to measure performance differences between
the two handshake protocols we support in QUIC.
4) New IETF draft versions
We are currently experimenting with both draft-27 and
draft-29, for 1% of users. We will increase that number
if results are promising. Our goal is to enable one of
these (or potentially subsequent drafts published by
the IETF) as our default version at some point in the
future. We're in the process of removing support for
IETF draft-25 and draft-28.
Feel free to send any questions to this list.
Cheers,
David
