Hi,

I have a Storage with high input traffic in a network, in add
192.168.16.8, and a playout in add 192.168.16.50.

I am using Packet Filter for to ensure low delay in streams of video
with samba, using real time, but i get poor results,
someone know a best AltQ/PF configuration for streams.

My Altq configuration:

queue root_em0 bandwidth 1Gb priority 1 qlimit 100 {SYSTEM_QUEUE}
queue  SYSTEM_QUEUE bandwidth 1Gb qlimit 100 {AVNQOS1, SYSYTEM_DEFAULT}
queue   AVNQOS1 bandwidth 100Mb priority 7 qlimit 10000 hfsc( ecn
realtime 100Mb upperlimit 100Mb )

But in Realtime m1 is 100Mb, m2 is 50MB and d is 18.

My Rule configuration:

pass out on em0 inet proto tcp from 192.168.16.8 to 192.168.16.50 tos
0x10 queue AVNQOS1

Thanks.

P.S. Sorry for my bad english.
