LARTC - Jan 2004 - Per Ip bandwidth

Hi there,

	I have two questions:

1)
	In the following setup:

tc qdisc add dev eth1 root handle 1: htb
tc class add dev eth1 parent 1: classid 1:1 htb rate 100Mbit
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 128Kbit 
tc class add dev eth1 parent 1:10 classid 1:11 htb rate 32Kbit ceil
128Kbit
tc class add dev eth1 parent 1:10 classid 1:12 htb rate 32Kbit ceil
128Kbit


	I have observed that if the user whois ip is going to class 1:11 has
more threads, that that fro9m class 1:12 then, there is no more fairness
in borrowing, so that user with 1:11 gets almost all the unused
bandwidth from the parent ( going up to 96Kbit/s ).
	

2)
	why do I get " qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] " at tc
qdisc ls dev eth0 right after booting the computer, without attaching
yet any qdisc ??


Thank for your ideeas.

well htb isn''t just for this case.
i would make one class and atach wrr/esfq qdisc to it. they''re made
esspecialy for
round-robin fairness. When i used wrr i''ve got absolute fairness (1 or
2 bytes difference :)

because there is default qdisc which is simple pfifo.
