Which services of Google supported by QUIC

[Van Tong]

Hi all,

I found that youtube is supported by QUIC.
I also capture packet when I upload file to Google driver, I found lots of QUIC packet. Is Google driver supported by QUIC?

Any body know how to define whether a service of Google supported by QUIC or not? Which service of Google is supported by QUIC ?

Thank you in advance!

Basically all Google services support QUIC these days. You can look for the Alt-Svc header in response headers from a Google server to confirm.

Thank for your quick response.

QUIC is implemented on the top of UDP. Is the accuracy of data transferring 100 percent?

For example, I think that Google mail need 100 percent of accuracy.

The connection to this site is supported by TLS v1.2.

However, I found that Alt-svc of Google mail:

alt-svc:

hq=":443"; ma=2592000; quic=51303431; quic=51303339; quic=51303338; quic=51303337; quic=51303335,quic=":443"; ma=2592000; v="41,39,38,37,35"

Yes, QUIC provides reliable delivery.

When I enable QUIC and log in Gmail, the connection is encrypted and authenticated by TLS1.2.

However, I got the alt-svc as in following:

alt-svc:

hq=":443"; ma=2592000; quic=51303431; quic=51303339; quic=51303338; quic=51303337; quic=51303335,quic=":443"; ma=2592000; v="41,39,38,37,35"

I just want to ask that Gmail whether is supported by QUIC or not? And why I got this?

This alt-svc means the same resource(gmail, in this case) you are accessing can be accessed via quic. 

• hq=":443" means the resource can be accessed on port 443 of the same host, using 'http over quic'.
  
• ma=2592000 means the information in the alt-svc is valid for 2592000 seconds, or 30 days.
• quic=51303339 means the server can talk in quic version 'Q039'.
  

Note there is a comma before quic=":443", the string before and after that comma are just different formats for the same information.

Also note the format is not standardized yet, to see what it looks like in the latest draft, go to: https://datatracker.ietf.org/doc/draft-ietf-quic-http/?include_text=1

Gmail is currently one of the very few Google services that does not use QUIC; this is temporary, and will likely change in the future.  Google Search, Calendar, YouTube and most other Google services do support QUIC.

I am somewhat surprised you got that alt-svc from Gmail;  I get "Alt-Svc: clear" whenever I try to talk to either gmail.com or mail.google.com.

[Van Tong]

Thank you for your response.
OK. I got "Alt-Svc:clear" when I access to mail.google.com. I misunderstand about this.

I have a question related to Google Hangout. Is Google Hangout supported by QUIC?
I just want to know exactly about this.

Accoreding to Alt-Svc, Hangout's web frontend, hangouts.google.com, does support quic. But it doesn't mean the hangout apps(on ios, andrioid, etc) use quic.

Thank you for your response.
