I understand that the last mile is going to be a congestion point, but
the idea of allowing a bidding war for priority access for that
capacity seems to be a path to madness.

Hi Chris,

Since prioritization would work ONLY when the link us saturated
(congested), without it, nothing is going to work well, not your
torrents, not your email, not your browsing.  By prioritizing the
traffic, the torrents might back off but they would still continue to
flow, they wouldn't be completely blocked, they would just slow down.
QoS can be a good thing for allowing your VIOP to work while someone
else in the home is watching a streaming movie or something.  Without
it, everything breaks once the circuit is congested.


It depends. If you're talking about prioritization of the end link, then,
that's one thing... If the ISP wants to implement prioritization there
based on the END USER's preferences, that's a nice value-add
service.

If you're talking about the aggregation point of several customer's
links, then, prioritizing customer A's Yahoo traffic because Yahoo
paid over customer B's torrent traffic when customer A and B have
paid the same for their connection is not so good, IMHO.
