Hiya all,
Could someone clarify for me the purpose of the
bandwidth parameter when used with hfsc? Please consider my queue (512Kb
max upload through the ADSL line):
altq on em1 bandwidth 500Kb
hfsc queue { ack, dns, ssh, other }
queue ack bandwidth 95%
priority 8 qlimit 500 hfsc (realtime 20%)
queue dns
bandwidth 95% priority 7 qlimit 500 hfsc (realtime 5%)
queue
ssh bandwidth 95% priority 6 qlimit 500 hfsc (realtime 20%)
{ssh_login, ssh_bulk}
queue ssh_login bandwidth 95% priority 6
qlimit 500 hfsc
queue ssh_bulk bandwidth 95% priority 5 qlimit
500 hfsc
queue other bandwidth 95% priority 5 qlimit 500 hfsc
(realtime 20% default)
My understanding was that "bandwidth
xx%" tells pf that the queue can only use xx% of the total parent queue
bandwidth and the various guides on the Internet say that it cannot go
above 100% which sort of makes sense. However what I want, for example,
is the 'other' queue to get all the upload bandwidth as long as there is
no acks or ssh traffic in the queue. If I set bandwidth 20% for other,
won't that mean that no matter what, the 'other' queue will only get a
maximum of 20% of the bandwidth (even if there is no ssh traffic
waiting?)
I think I haven't quite understood this properly but
perhaps someone could clarify it. I found a lot out from calomel.org's
excellent page but that's the only bit that confused me.
Thanks
help
