Ah. Yes, this way changing to a new 5-tuple will help for some period of time, though it makes QUIC a poor choice for e.g. video streaming then :-( > QUIC allows for multiple connections on the same 5-tuple Well, sorry, this is up to the terminology. The purpose is just to make sure an incoming packet is in fact a response to something outgoing in the past. How many connections or streams go through those packets is out of scope of the problem.
