It seems that configuration like
qdisc(CBQ)
|
class
| |
class1 class2
bounded bounded
doesn't work perfect.The more stable ( accurate ) configuration would be
qdisc(cbq) 1:0
|
class 1:1
|
qdisc(cbq) 2:0
| |
class 2:1 class 2:2
|
qdisc(tbf) 3:0
Now when class 2:1 have rate 10Mbit and class 2:2 = 70Mbit
i can have 9.05 and 72.774

I test for CBQ and get the same result.
This question I asked before, it's maybe weight, avpkt, cbq problem...
I change the avpkt to 500Kbit(I don't know why???) and get better accuracy,
maybe you can try this.
Another way is change your queueing disciplines(cbq) to tbf, it's really
more stable than cbq, it won't get jitter when your avpkt is change.
