[FUG-BR] PF + ALTQ com PRIQ

[Rafael - Gmail]

Nossa Alessandro, muito obrigado!
Tive lendo o man do pf.conf, e achei o que o HFSC faz

"hfsc  Hierarchical Fair Service Curve.  Queues attached to an interface 
build a tree, thus each queue can have further child queues. Each queue can 
have a priority and a bandwidth assigned. Priority mainly controls the time 
packets take to get sent out, while bandwidth has primarily effects on 
throughput. hfsc supports both link-sharing and guaranteed real-time 
services. It employs a service curve based QoS model, and its unique feature 
is an ability to decouple delay and bandwidth allocation."

Com certeza você já deve saber disso, mas tive o prazer de postar, pois 
alguém um dia vai precisar ... realmente muito bom para o que eu desejo 
implementar.
Vou testar e retorno pra lista o resultado.

Att,
Rafael Simão

olha este exemplo
# 768kbit upload, using hfsc (78kB/s 624kbit/s max via ftp, pftop
shows 85kB/s or 680kbit/s)
altq on $ext hfsc bandwidth 768Kb qlimit 150 queue { root_out }
# only give out 95% of the bandwidth, this helps improve overall queue
handling, esp latency
 queue root_out bandwidth 95% hfsc(linkshare 89% upperlimit 89%)
{oCtl, oAck, oDly, oBrst, oRel, oTput}
    # icmp control traffic
    queue oCtl  bandwidth 16Kb  qlimit 15   hfsc( realtime 16Kb
linkshare 16Kb )
    # tcp ack traffic
    queue oAck  bandwidth 32Kb qlimit 150   hfsc( realtime 64Kb
linkshare 32Kb red )
    # latency sens traffic
    queue oDly  bandwidth 160Kb qlimit 50  hfsc( realtime 164Kb
linkshare 160Kb )
    # burst-prone traffic (256Kb of realtime for the first 6 seconds,
then drops to 94Kb)
    queue oBrst bandwidth 84Kb qlimit 50  hfsc( realtime (256Kb 6000
94Kb)   linkshare (192Kb 6000 84Kb) )
    # reliable traffic
    queue oRel  bandwidth 128Kb qlimit 100  hfsc(
linkshare 128Kb ) { oRelTCP, oRelUDP }
        queue oRelTCP bandwidth 64Kb qlimit 50 hfsc(
linkshare 64Kb default red )
        queue oRelUDP bandwidth 64Kb qlimit 50 hfsc(
linkshare 64Kb)
    # throughput-oriented traffic
    queue oTput bandwidth 100Kb qlimit 25   hfsc(
linkshare 100Kb red )

### Outgoing Queues on Internal Bridge Interface (from internet to
local) Traffic Conditioning/Shaping

altq on $int hfsc bandwidth 1240Kb queue { root_in }
 queue root_in  hfsc(linkshare 95%) {iCtl, iAck, iDly, iBrst, iRel,
iTput }
    queue iCtl        bandwidth 3%  qlimit 15   hfsc( realtime 16Kb
          linkshare 16Kb              )
    queue iAck        bandwidth 20% qlimit 1000 hfsc( realtime 64Kb
          linkshare 64Kb       red    )
    queue iDly        bandwidth 20% qlimit 25   hfsc( realtime 128Kb
          linkshare 128Kb             )
    queue iBrst       bandwidth 20% qlimit 25   hfsc( realtime (256Kb
8000 128Kb)  linkshare (512Kb 8000 128Kb)
    queue iRel        bandwidth 20% qlimit 150  hfsc( realtime 512Kb
          linkshare 256Kb      default)
    queue iTput       bandwidth 10%  qlimit 50   hfsc(
         linkshare 128Kb
