Hello
I am using htb (krenel 2.6.14.3 + esfq patch from 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 :)

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. - Jody On 12/14/05, Anton Glinkov <lartc@ssi.bg> wrote:> > Hello > I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the > bandwidth.

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

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. - Jody Salim wrote:> What confuses me is, how the popular HTB script ''wondershaper'' works! > The sum of its subclasses'' rates is way over the parent''s rate. > > ----- Original Message ----- > *From:* Jody Shumaker <mailto:jody.shumaker@gmail.com> > *To:* Anton Glinkov <mailto:lartc@ssi.bg> > *Cc:* lartc@mailman.ds9a.nl <mailto:lartc@mailman.ds9a.nl> > *Sent:* Friday, December 23, 2005 4:22 AM > *Subject:* Re: [LARTC] exact 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.
