LARTC - Jul 2006 - how different qdisc at root and leaf working???

i doubt about ruleset in mastershaper demo about
why use hfsc at leaf class but inner class use htb???
how different for manage traffic like it????

/bin/false qdisc add dev eth1 handle 1: root htb default 1
/bin/false class add dev eth1 parent 1: classid 1:1 htb rate 2048Kbit

######### Incoming Rules

######### chain HB
/bin/false class add dev eth1 parent 1:1 classid 1:21 htb rate 128Kbit ceil
512Kbit prio 2 quantum 1532
######### generating pipes for HB
/bin/false class add dev eth1 parent 1:21 classid 1:299 htb rate 256Kbit ceil
256Kbit prio 4 quantum 1532
/bin/false qdisc add dev eth1 handle 299: parent 1:299 hfsc

from above command, Is it true i think ...???
use HTB only for shaper bandwidth in each sevice with setting parameter rate???
use HFSC only for manage dequeue traffic after shaper bandwidth from inner
class???

How different to use 2 algorithm????

thankyou

Raku,

 : /bin/false qdisc add dev eth1 handle 1: root htb default 1
 : /bin/false class add dev eth1 parent 1: classid 1:1 htb rate 2048Kbit
 : /bin/false class add dev eth1 parent 1:1 classid 1:21 htb rate 128Kbit ceil

You must have renamed "tc" to "false".  :)

 : use HTB only for shaper bandwidth in each sevice with setting parameter
 : rate???
 :
 : use HFSC only for manage dequeue traffic after shaper bandwidth from
 : inner class???

In the above traffic control structure, you have not specified any 
classes for the HFSC qdisc.  That means it''s effectively doing 
nothing (useful).

Check out my earlier mail--and good luck,
