Yes, but does that matter? If there's extra capacity on the link,
Netflix runs at full rate. If there is not extra capacity Netflix
rates down to prevent congestion. While streaming video (including
Netflix) uses a lot of bandwidth, I don't see Netflix causing
congestion. It gets a bad wrap, and I think that's unfair because
Netflix is actually really efficient and really conscientious
compared to others.<br>

Across several eyeball networks I'm not seeing any noticeable
increase <br>
in peak (95%) demand between now and January. Since Netflix <br>
automatically scales down data rates in the event of
congestion, the <br>
only thing I foresee forcing Netflix to reduce data rates
[ahead of any <br>
congestion] would accomplish is causing excess link capacity
to go <br>
unused (wasted). This sounds like a policy decision made
without a <br>
technical argument... e.g. not a data driven decision, but a
decision <br>
made out of fear or panic.<br>
