[LARTC] ESFQ not working?

[LARTC] ESFQ not working?

[Osgaldo Suanzes]

hi, there.

#!/bin/sh
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1: htb default 1
tc class add dev eth1 parent 1: classid 1:1 htb rate 32kbps
tc qdisc add dev eth1 parent 1:1 handle 10: esfq

    This is my script to shape my download traffic on eth1 down to
32KB(ADSL%6kbit).
    How can I be sure the esfq disc is properly attached to the class?
    If I comment out the ESFQ line, I have quiet the same results of
behaviour when I start downloading
    from different boxes on that lan attached to eth1. (2 boxes downloading
are not having 50% each from the bandwitdth,
    and 3 boxes downloading  neither have 33,3% of the available bandwidth)
ESFQ is supposed to be "fair" ? or not?

            Something wrong on the script? If not how can I enhance my
settings?
            Is there a way to see that ESFQ, SFQ is working?


                    Thanks , Osgaldo

Yes.  But it creates fairness between flows.  And a flow is determined by 
ports and ip-addresses.
I never tried esfq so I don't know how it should behave.

Not that I know.

I personally couldn't achieve this. Maybe the authoer can help us?
