I've seen Bittorent use UDP and have as many as 50 UDP sessions per client running it. At that point I rate limit them to 256k and wait for the phone call.

Box 126 Bucyrus, OH 44820 419-562-6405 _____ From: [email protected] [mailto:[email protected]] On Behalf Of Bret Clark Sent: Tuesday, September 14, 2010 8:56 AM To: WISPA General List Subject: Re: [WISPA] Taking the plunge First at the interface level, you need to enable WMM. Then I set up the following rules which ensures that DSCP sets layer 2 priority WMM needs: "/ip firewall mangle add action=set-priority chain=prerouting comment="VoIP WMM " disabled=no new-priority=from-dscp passthrough=yes protocol=\ udp " Most VoIP services tend to use DSCP of 46. Then I set a somewhat broadbase firewall/queue rule which basically says UDP packets should get preference since 99.9% of VoIP is UDP and I make it the first queue rule before all others. "/ip firewall mangle> add action=mark-packet chain=forward comment=VoIP disabled=no in-interface=ether1 new-packet-mark=VoIP \ passthrough=no protocol=udp" "/queue simple add burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s comment="" direction=both disabled=no dst-address=0.0.0.0/0 interface=all \ limit-at=0/0 max-limit=0/0 name="VoIP Traffic" packet-marks=VoIP parent=none priority=1 queue=synchronous-default/synchronous-default \ total-queue=default-small" These rules can be massaged quite a bit to be more specific since a lot of other apps use UDP too. Some things we'll do to make the rule more specific is find out the users VoIP provider and then setup the queue based on the VoIP's IP block.

We also added queue rules in both the CPE and AP to ensure that VoIP traffic got priority not just at layer 2, but layer 3.
