> 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? I don't doubt that's true but I would love to see a breakdown. If an intermediate router is using Randomized Early Detection (RED) and is congested within the randomized packed drop region, then you could easily see one random packet in the middle of a stream dropped, with other streams unaffected.
