I have found CBQ to be very inaccurate (as others on the list)
I have created a structure as follow
Root (10mbit)
|
CBQ class (bandwidth=1mbit, rate=10mbit)
|
CBQ qdisc (bandwidth=1mbit)
Now when i send excess data to the tune of 1.3mbit, cbq lets it thru.
If i increase it beyond that, CBQ suddenly wakes up and throttles it down
to about 0.8Mbit!
Are there any explanations? If i am sending fixed size packets, should i
set the 'avpkt' to that size?
I havent even able to use HTB correctly since a small burst size kills my
thruput.
Any ideas about CBQ/HTB or anything which will throttle my bandwidth to
1Mbit accurate *and* allow me to create qdiscs within. (Hence TBF is ruled
out). My HTB script is given below i am no clue why it doesnt work.
-----------------------------------------------------------------------
BANDWIDTH="bandwidth 10Mbit"
LIMITBW="1Mbit"
$TC qdisc add $DEVICE root handle 1: htb
# This HTB class rate limits everyting to 1Mbit
$TC class add $DEVICE parent 1: classid 1:1 htb rate $LIMITBW ceil
$LIMITBW burst 2k
