How can I make a single queue don't borrow ALL the traffic?
upperlimit
OK, my question was badly expressed.
I have already written the problem a few times: the question is not to
put an upper limit to a queue but to don't make it "monopolize" all the
bandwidth because of its great amount of traffic, leaving queues with
low traffic with ALL packets dropped (as you van see in the pftop
snapshot I sent).
I already explained it with the following example:
Both users A and B have an assigned bandwidth of 1 bps.
User A currently requires 4 bps.
User B currently requires 100 bps.
There are currently available 10 bps.
I'd like that the 10 bps would be equally distributed to both users (as
they have the same assigned bandwidth), so both had potentially 5 bps.
User A uses 4 bps and leaves 1 bps to user B that so uses 6 bps.
This is the "fair" bandwidth assignment I'd like to implement.
Indeed it seems that, as user B requires 25 times more bandwidth of user
A, then it is assigned almost ALL bandwidth, and user A is not able to
use more then it's committed 1 bps, and so 3 out of 4 bits are dropped!
in this case it is probably not super important to see your
whole pf.conf, but without seeing the service curves you're
applying to the queues, it's a bit of flying blind.
it seems to me that what you want to do is feasible with HFSC.
posting your altq section would be helpful in trying to
resolve the problem you're seeing.
Attached is the part of the pf.conf files that defines that part of
queues. As you can see it's pretty simple. (Only wh1_i has an upperlimit
because all the others have a limit in their router.)
Thanks.
