That's becouse the _real_ scenario will look like this:
root->parent_all_hosts->client_host_1->prio
->dfl
->client_host_2->prio
->dfl
->client_host_3->prio
->dfl
->client_host_N->prio
->dfl
I'will use this parent_all_host class to set the total_real iface rate.
I've posted the reduced example for simplicity and to isolate the real
problem.
Anyway i've tested a new version of the example attaching the client direct to
the root class witouth any luck. Script that i use for testing attached. Also
full tc stadistics, taked from begining and after aprox 3~4 minutes.
Here some highlights
This is 'dfl' class
class htb 1:7005 parent 1:7000[...]rate 23000bit ceil 230000bit
Sent 4521301 bytes 3095 pkt (dropped 0, overlimits 0 requeues 0)
lended: 467 borrowed: 2628 giants: 0
tokens: -2193687 ctokens: 8085
This is 'prio' class
class htb 1:7004 parent 1:7000[...]rate 207000bit ceil 230000bit
Sent 1741028 bytes 1168 pkt (dropped 0, overlimits 0 requeues 0)
lended: 1168 borrowed: 0 giants: 0
tokens: 397670 ctokens: 8085
As you see, after 3 minutes the lower rate class has sent 3000 packets vs 1000
packets from the high rate one. Don't know what to think...

no complaints

My test bed at this moment is a gentoo-kernel-2.6.14 in a x86 gentoo, in the
server side(iproute2-2.6.11.20050310-r1), and a user-mode-linux-skas3-2.6.14.
in the client side, with vde_switch daemon listening in a tuntap device. I
suppose that htb is device independet, i hope it does not matter.
I have production enviroments waiting for my results (a couple of small local
ISPs, an a similar WISP), but the problem is that im coding this far from
home, and beside the servers, i have no access to any of the clients to force
the rates.
If you think this enviroment is somewath "buggy" plz tell.
Txs for your response!
