[LARTC] Isolated Class in HTB

[LARTC] Isolated Class in HTB

[arisantois]

Hi All

I have a newbie question here.. I use HTB to manage bandwith in my
University. We have 5 Faculties that connected directly to my office, So we
made 6 classes with one class as Default class.

[root@gw-konsorsium root]# tc class show dev eth0
class htb 1:10 parent 1:2 leaf 10: prio 0 rate 256Kbit ceil 426Kbit burst
15Kb cburst 2Kb
class htb 1:2 root prio 0 rate 10Mbit ceil 10Mbit burst 15Kb cburst 14704b
class htb 1:20 parent 1:2 leaf 20: prio 0 rate 86Kbit ceil 426Kbit burst
15Kb cburst 2254b
class htb 1:30 parent 1:2 leaf 30: prio 0 rate 86Kbit ceil 426Kbit burst
15Kb cburst 2254b
class htb 1:40 parent 1:2 leaf 40: prio 0 rate 86Kbit ceil 86Kbit burst
15Kb cburst 2254b
class htb 1:50 parent 1:2 leaf 50: prio 0 rate 64Kbit ceil 64Kbit burst
15Kb cburst 1680b
class htb 1:60 parent 1:2 leaf 60: prio 0 rate 1Kbit ceil 10Mbit burst 15Kb
cburst 14704b

[root@gw-konsorsium root]# tc qdisc show dev eth0
qdisc sfq 60: quantum 1514b perturb 10sec
qdisc sfq 50: quantum 1514b perturb 10sec
qdisc sfq 40: quantum 1514b perturb 10sec
qdisc sfq 30: quantum 1514b perturb 10sec
qdisc sfq 20: quantum 1514b perturb 10sec
qdisc sfq 10: quantum 1514b perturb 10sec
qdisc htb 1: r2q 100 default 60 dcache 0
 deq_util 1/244 deq_rate 161 trials_per_deq 1
 dcache_hits 0 direct_packets 4

My problem is One faculty (Class 1:40) don`t want to borrow and lend
bandwith to other classes.
I use SFQ as queing discipline. In CBQ with TBF we can do ISOLATED and
BOUNDED.. How to do it in HTB .?

Thnx

class htb 1:40 parent 1:2 leaf 40: prio 0 rate 86Kbit ceil 86Kbit burst
15Kb cburst 2254b

It can't borrow from other because rate 86kbit and ceil 86kbit but it can share its
bandwith with other classes

[Martin Devera]

Use independent root. I.e. create 1:40 with 1:0 as root not 1:2.
Roots of hierarchy are isolated each against other.
And like someone other wrote, use ceil to bound both 1:2 and 1:40
to appropriate values.

I see.. But Can I attach more than one root class in one Device
(Ethernet)..? I am sorry but I don`t find any case or example like this
before..

Thnx In Advanced

You can only attach one qdisc to a device.  If you want to have a class that 
will not borrow, nor lend from/to other classes, you can do this (copied from 
your setup) :

root qdisc
class 1:1 rate = ceil = 426 Kbit
   class 1:40  rate = ceil = 86 Kbit
   class 1:2  rate = ceil = 340 Kbit (426 - 86)
     class 1:20 rate = 86, ceil = 340 Kbit
     class 1:30 rate = 86, ceil = 340 Kbit
     class 1:50 rate = 64, ceil = 64 Kbit
     class 1:60 rate = 1, ceil = 10Mbit (Why ???)

class 1:40 will never lend nor borrow bandwidth from the other classes.
