<div>I feel like you're rather optimistic about the deployment of fq</div>
<div>Also, you mention uplink in home gateways. There you not only have bittorrent but also a lot of personal cloud going up, a lot of video calls.</div>
<div><br>
</div>
<div>There IW10 without fq is going to be bad. In the US your are going to have pie on cable if I am not wrong...uhm...</div>

One saving grace of the IW10 deployment so far is that it is (mostly)<br>
limited to Linux, and that methods, such as pacing/initial<br>
spreading/fq, to cope with it better, are developing concurrently.<br>
<br>
It's not all bad - on GigE ethernet networks, it's ok, IW10 may well<br>
be useful in wifi packet aggregation, etc, but it does do potentially<br>
a great deal of damage to networks running at very low rates. My<br>
concern has largely been the collateral damage it causes network<br>
uploads from the edge, where vastly lower rates are common.<br>
<br>
It could be mitigated further in a desktop deployment by (for example)<br>
sticking with IW4 for everything going out a default gateway, and<br>
steps taken to make sure applications like bittorrent/transmission<br>
used a lower default. I have no idea what the IW is for android, but<br>
that should perhaps be lower also. I think ledbat shouldn't have an IW<br>
at all....<br>
<br>
I would not mind if IW information was carried as a payload in dhcp/hnetd/etc...<br>
<br>
I have no problem with people suggesting changes here that require<br>
"changing the entire internet". We seem to have done that a couple<br>
times, already. :) It would be nice if we could calculate the damage<br>
it causes along whatever portion of the internet is running at below<br>
10Mbit....<br>
<br>
A simple question - how many T1 lines are left in the world?<br>
