[LARTC] ESFQ

["Vladimír Třebický" <druid@mail.cz>]

Hi,

I have little problem with ESFQ. I set root qdisc cbq on eth1 (which is on
LAN side of network), then 1:1 cbq class with exact bandwidth and its two
child - cbq 1:10 and cbq 1:20 with 1:1's bandwidth divided. I also set two
ESFQ perturb 10 hash dst on those two classes. But when someone starts to
download with 100 threads, he has much more bandwith than someone with only
one. I understand that this is exactly what esfq should solve, so I think
that somewhere on my side is mistake :-( This is my configuration:

tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit avpkt 1000 cell 8

tc class add dev eth0 parent 1: classid 1:1 cbq bandwidth 10Mbit rate 256
Kbit weight 2.56 Kbit prio 1 allot 1514 cell 8 maxburst 20 avpkt 1000
isolated

tc class add dev eth0 parent 1:1 classid 1:10 cbq bandwidth 10Mbit rate 32
Kbit weight 3.2 Kbit prio 1 allot 1514 cell 8 maxburst 18 avpkt 100 isolated
tc class add dev eth0 parent 1:1 classid 1:20 cbq bandwidth 10Mbit rate 224
Kbit weight 2.24 Kbit prio 2 allot 1514 cell 8 maxburst 2 avpkt 1500 bounded

tc qdisc add dev eth0 parent 1:10 handle 10: esfq perturb 10 hash dst
tc qdisc add dev eth0 parent 1:20 handle 20: esfq perturb 10 hash dst

iptables -t mangle -A PREROUTING -m length --length 0:500 -j MARK --set-mark
3
iptables -t mangle -A PREROUTING -m length --length ! 0:500 -j
MARK --set-mark 4

tc filter add dev eth0 parent 1: protocol ip handle 3 fw flowid 1:10
tc filter add dev eth0 parent 1: protocol ip handle 4 fw flowid 1:20

Thank you very much for answer,

Vladimir Trebicky
