LARTC - May 2003 - dont know why htb is not working

Stef or any "qos" guru!!: 

hi, im managing a 1 mega connection for a company...i use debian, kernel 2.4.20.
my idea is to priorice all www traffic..but i dont know some stuff about
matching with the u32 filter.
can anyone give me some idea of what is goinng worng here?
about kazza, bseiides filtering the out, should filter the ingress too?

well, thanks for your time

mi script is this: 

DOWNLINK=1024
UPLINK=1024
DEV=eth0

tc qdisc del dev $DEV root    2> /dev/null > /dev/null
tc qdisc del dev $DEV ingress 2> /dev/null > /dev/null

tc qdisc add dev $DEV root handle 1: htb default 20

Remove the burst and the prio parameters from your htb classes.  The burst is 
too low to get some good shaping.  And different prio''s can introduce
high
delays.

And why do you have the same filter for source and destination ????

This is not needed because 1:20 is the default htb class.

but if i remove the prio, i wont get the packet priorization as i wanted..and as
i read, htb know thrug the prio who can "lend" BW....is it like that?

i put src and dst because im not sure how to match the packet

thanks Stef.

Not really.  Each class can send it''s rate.  If the parent has more
bandwidth
left, prio is used.  And the lowest prio class will also have the lowest 
delays.  BUT if you send more data then the rate in a low prio class, the 
latency can bevery high.

Ok.
