Exactly. And note how they just so happen to pick 11 total flows (10
competing, one video) to share the bottleneck, putting the per-flow
throughput just below the rate needed to go up one quality level. What a
coincidence. At least it shows how difficult it is to design experiments
that put fairness queueing in a bad light ;)
Oh, and of course HAS is in itself a hack to work around badly managed
queues in the network. In a nicely fairness queued world, we could do
away with HAS entirely and just, y'know, stream things at the desired
rate...
