XTLS Flow #55

Closed vVxiliVv closed 4 years ago

vVxiliVv commented 4 years ago

I am a noobie when it comes to more advanced tls subjects and i can't find info about it with google.

What is xtls exactly and what is the difference between xtls-rprx-origin, xtls-rprx-origin-udp443.

i am tring to learn new things.

Thanks!

yeah i have read that multiple times with translate. What is the difference between those two options, how does it changes the data flow or what does it even do?

VLESS client will stop UDP/443 requests when using xtls-rprx-origin in order to stop QUIC, but will not stop these requests when using xtls-rprx-origin-udp443.

Thanks for the answer! Why does this needed to be implemented? So it does not really affect the encryption. Also, when i configured quic, on 4.31.0 (server) and with the latest v2rayng, nothing happened, logs showed nothing.

Wich stream is better, quic or tcp. Quic uses udp as far as i know, can i use it with allowinsecure true? I have unlimiteddeezer data, and when i change the servername to api.deezer.com i have unlimited data. I am tring to max out the throughtput of my server that is why i am asking.

Thank you for your time!

Stopping QUIC means preventing apps like YouTube from choosing UDP QUIC rather than TCP TLS, which will make XTLS meaningless (as XTLS only works for TCP TLS above, not UDP QUIC over TCP).

Got my answer, thanks!
