0-RTT #9

Closed aretana closed 1 year ago

aretana commented 2 years ago

Is there any advantage to using 0-RTT when opening a QUIC connection?

In general, the exchange of the initial OPEN message could be accelerated -- is this an advantage?

aretana commented 1 year ago

There's no advantage for initial session establishment, but maybe for connection resumption (GR) ???

"However, 0-RTT provides no protection against replay attacks; see Section 9.2 of [QUIC-TLS]."

0-RTT might be helpful to permit session resumption happen slightly faster, but given the point is to resume a session with good security properties, the text above might bother our security folk.

I don't think there's a reason to push 0-RTT cases for BGP.
