Re: [LARTC] any errors in this script?

["Atahualpa Jones" <atahualpa@gmx.at>]

Hi,

I would suggest adding an sfq qdic to class 1:10, 1:11 and 1:12:

tc qdisc add dev ppp0 handle 2:0 parent 1:10 sfq perturb 10
tc qdisc add dev ppp0 handle 3:0 parent 1:11 sfq perturb 10
tc qdisc add dev ppp0 handle 4:0 parent 1:12 sfq perturb 10

nothing else would have to be changed, sfq makes sure that when your upload
is maxed no connection can dominate over others and everyone gets a fair
amount of the bandwidth.

For more info on sfq read chapter 9.2.3 of the LARTC howto.

Regards,
Ata
