Attached to: Vint Cerf Says Fix the Net With More Pipe  Well,
the internet probably does need more bandwidth to support
Netflix.  And I'm not a fan of QoS to get better streaming video
either. But is Cerf giving up on fixing the problems with
streaming (and any realtime internet work) that we know about,
bufferbloat? I heard about that from Jim Gettys (thanks to a
tweet from John Carmack). Here's a two-page intro in IEEE
magazine or a (more interesting IMHO) PDF slide presentation
with nice graphs and there is other advice and documents and
code on that bufferbloat website.  See, the problem with
streaming isn't just bandwidth, it's latency, and the
variability thereof. We always measure and marketers talk about
bandwidth, but only rarely if ever about latency. Thus ISPs
don't optimize for it as a rule. The result? You get these
occassional 6-second lags and other phenomena and little econom
