Thing is, it did not work for me, because of that exact reason. I had
issues with it ignoring rates and in general not giving the lower
latency I was going for. I really wish someone would update it.
lartc.org is broken right now, but I believe the version up there is 3
years old.

What confuses me is, how the popular HTB script 'wondershaper' works!
The sum of its subclasses' rates is way over the parent's rate.

Your subclass's combined rate's should never exceed your parent
class's rate, and in this case your parent class is 5mbit, yet
your subclasses have a combined guarenteed bandwidth of 6mbit. In
my setup, the root classes rate is followed strictly. With
burst, it may go over temporarily but over say a minute's time,
the bandwidth is pretty close to the set rate, usualy within
~0.4%. I'm unsure on what the behavior is when you allocate more
bandwidth to subclasses than the root, but it may be the reason
you're not seeing accurate results.

Hello
I am using htb (krenel 2.6.14.3 <http://2.6.14.3> + esfq patch
from fatooh.org <http://fatooh.org>) to limit the
bandwidth. But I want the absolute maximum rate to be for
example 5Mbit
and not to exceed it.
here is the script:
$tc qdisc add dev ${NETIF} root handle 1 htb r2q 4
$tc class add dev ${NETIF} parent 1: classid 1:21 htb rate
5Mbit ceil 5Mbit
$tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate
2Mbit ceil
5Mbit prio 1
$tc class add dev ${NETIF} parent 1:21 classid 1:102 htb rate
1Mbit ceil
5Mbit prio 2
$tc class add dev ${NETIF} parent 1:21 classid 1:103 htb rate
3Mbit ceil
5Mbit prio 3
when I don't specify burst the flow always exceeds 5Mbit
when I try to play with it (the burst) for example turning it
off completely
burst 0 cburst 0 for parent and children classes the rate
falls ot 2-3 Mbits
removing the esfq qdiscs doesn't change anything...
I want exact rate of 5Mbit for the parent class and no more?
any suggestions are welcome :)
