[LARTC] About HFSC ?

[Sébastien CRAMATTE]

Hello,

I’ve read this Article avout VOIP and HFSC
http://automatthias.wordpress.com/2006/06/30/hfsc-and-voip/

I’ve got few questions ?

Considering this

tc class add dev $DEV parent 1:1 classid 1:2 hfsc \
rt m1 ${UPLINK}kbit d 50ms m2 $[1*$UPLINK/10]kbit \
ls m1 ${UPLINK}kbit d 50ms m2 $[3*$UPLINK/10]kbit \
ul rate ${UPLINK}kbit

rt = realtime curve
ls = linksharing curve

but
m1 = ?
m2 = ?
d = dmax ?

I’ve found this article too
http://linux-ip.net/articles/hfsc.en/

And for example this line is quite diferent !

tc class add dev eth0 parent 1:10 classid 1:12 hfsc sc umax 1500b dmax
30ms rate 100kbit ul rate 1000kbit

Does anyone could you light me ?

Regards
