tc: using hfsc with stab/atm linklayer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi list,

I'm currently implementing a shaping solution based on the hfsc qdisc. I've seen that the htb qdisc (and others) have a linklayer option, with which you can compensate for atm cell padding.

The hfsc qdisc does not have such an option. Tc does have a generic stab option, though. Does anyone know if that is functional with hfsc? E.g. will the following command provide me with a hfsc root qdisc that correctly compensates for atm cell padding?*

tc qdisc add dev eth1 stab linklayer atm root handle 1: hfsc

.. or will I have to use htb instead?

I'm using kernel 2.6.32.9 with advanced routing options and qos etc (and julian anastasov's routing patches). * For simplification I have not (yet) set the other stab options: mtu, mpu and overhead, as explained here: http://ace-host.stuart.id.au/russell/files/tc/tc-atm/

Thanks!
