> One specific question I've had is on a lossy network are there really that many situations where you would have packet loss on one QUIC stream but not most/all the others? This isn't the advantage. The advantage is that if you have 10 different streams and a low loss rate, the impact of each packet lost would be much smaller. Consider a voip call with an architecture where each person's audio is served as a separate stream from a central server. With head of line blocking, every packet lossed causes a slight stutter in the whole conversation because even if the lost packet is from someone not talking, you have to wait for that packet of silence before decoding the packet from the person speaking. With QUIC, the extra latency only affects the individual stream, so the conversation won't stutter when the person not talking wasn't the one who's packet got lost.
