Speaking from my own experience, I would say that "the point" is that
when a user has, for instance, a DSL line running at 3.0mbps down and
256kbps up, it is very easy to saturate the outgoing bandwidth,
resulting in queues of up to 1-2 seconds for outgoing packets at the
DSL modem. <br>
<br>
The ADSL line that I use for my VoIP needs is somewhat faster than
this, clocking in at 768kbps upstream, but I nevertheless find it very
beneficial to send my VoIP packets to the "head of the queue" using a
Linux bridge that I have inserted into my network between my DSL CPE
(bridge) and the rest of my network. <br>

What's the point?<br><br>You can prioritise as much as you like at your own end, but as soon as it leaves<br>your premises and enters the 'net, all bets are off!<br><br>Even the contention ratio of the DSL circuit (as provided by your ISP) can kill you.
<br><br>QOS is really only useful in a point-to-point scenario, or in a meshed network<br>that honors QOS on all links.<br><br>If you really want to experiment, grab an old PIII for $50 off e-bay, and setup<br>a linux box as a router behind your DSL modem. You can play with QOS as much as
<br>you like then, without forking out $500.<br><br><br>==========================================<br>Rod Bacon<br>Empowered Communications<br>Ground Floor, 102 York St. South Melbourne<br>Victoria, Australia. 3205<br>Phone: +613 99401600 Fax: +613 99401650
