Hi
I'm using wondershaper like script. But noticed imperfect scheduling.
By googling, I found some patches that takes the aal5 atm overhead in
the scheduling algorithms.
http://www.adsl-optimizer.dk/ADSL-optimizer/
Before trying it, has anyone tried these patches? they apply on 2.4.29
kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can't try
these easily.
They should be OK as long as you are sure about your overheads.
I use something similar and use ceil 286kbit while synced at 288kbit
without problems.
If your modem is connected by eth rather than ppp then htb/whatever will
see the packet size as ip len + 14 - so you need to account for that.
I think that produces a corner case (overhead < 14) where you would need
to put in a negative number - I don't think that will work, but haven't
tried.
Andy.
