[LARTC] configuration problem

[LARTC] configuration problem

[Victor]

I must say that the sum of rates of child classes is higher than the rate
of class 1:1(parent class);
My configuration:
tc qdisc add dev eth1 root handle 1: htb default 2
tc class add dev eth1 parent 1: classid 1:1 htb rate 500Kbit prio 1
quantum 2000
tc class add dev eth1 parent 1: classid 1:2 htb rate 9999Kbit prio 1
quantum 2000


Classes:
tc class add dev eth1 parent 1:1 classid 1:601 htb rate 1Kbit ceil 500Kbit
prio 0 quantum 2000
tc class add dev eth1 parent 1:1 classid 1:602 htb rate 64Kbit ceil
500Kbit prio 0 quantum 2000
.
. (255 clases total)
.
tc class add dev eth1 parent 1:1 classid 1:6fe htb rate 128Kbit ceil
500Kbit prio 0 quantum 2000
tc class add dev eth1 parent 1:1 classid 1:6ff htb rate 1Kbit ceil 500Kbit
prio 0 quantum 2000


Filters
tc filter add dev eth1 parent 1: prio 1 handle 4: protocol ip u32 divisor 256
tc filter add dev eth1 parent 1: prio 1 protocol ip u32 ht 800:: match ip
dst 81.97.105.0/24 hashkey mask 0x000000ff at 16 link 4:
tc filter add dev eth1 prio 1 protocol ip u32 ht 4:01 match ip dst
81.97.105.1 flowid 1:601
tc filter add dev eth1 prio 1 protocol ip u32 ht 4:02 match ip dst
81.97.105.2 flowid 1:602
.
.(255 filters total)
.
tc filter add dev eth1 prio 1 protocol ip u32 ht 6:fe match ip dst
81.97.105.254 flowid 1:6fe
tc filter add dev eth1 prio 1 protocol ip u32 ht 6:ff match ip dst
8197.105.255 flowid 1:6ff

The problem:
I have a user with a rate of 64Kbit ceil 64Kbit.
His trafic is like this: He touches 64Kbit on a graphic, then he drops
down to a few Kbits, and it keeps repeating this.
He shouls stay at 64Kbit constantly.
This does not heapens all the time.
Some times works just good.
I want to know if is something wrong with this configuration.
I use a similar configuration for upload.

Thank you
