hi,

Thank you for your suggestion.
Unfortunately I have found only generic sentences and not the answer to my question: how exactly "priority" works?

Or, from a practical point of view: a queue with an high "priority" parameter gets ALL the bandwidth he wants from queues with lower "priority" (except, maybe, for the "realtime" one)?

well, if i get you right, your question is answered here: http://calomel.org/pf_hfsc.html
quote:
Cbq and HFSC queues with a higher priority are preferred in the case of overload.

OK, but the word "preferred" is little generic for me, especially because this sentences is used to differentiate from the behaviour of the "Pri" queues: "Priq queues with a higher priority are always served first".

So, in HFSC queues with higher "priority" are not ALWAYS served before queues with lower "priority"?

Maybe the "realtime" bandwidth is alway served first and then the "priority" parameters enters in action?

Queues with higher "priority" gets ALL the bandwidth they need regardless of the "linkshare" of queues of lower "priority"?


Bye.
