(Sorry if this appears twice) Hi, I have a Linux box which acts as a router (NAT) and has VoIP software. I want the VoIP traffic to have the highest priority. So I used a script like this: #!/bin/sh DEV=ppp0 TC=tc $TC qdisc del dev $DEV root > /dev/null 2>&1 $TC qdisc add dev $DEV root handle 1: htb default 30 $TC class add dev $DEV parent 1: classid 1:1 htb rate 96kbit burst 15k $TC class add dev $DEV parent 1:1 classid 1:10 htb rate 94kbit burst 15k prio 0 $TC class add dev $DEV parent 1:1 classid 1:20 htb rate 1kbit ceil 1kbit burst 1k prio 1 $TC class add dev $DEV parent 1:1 classid 1:30 htb rate 1kbit ceil 90kbit burst 1k prio 7 $TC qdisc add dev $DEV parent 1:10 handle 10: sfq perturb 10 $TC qdisc add dev $DEV parent 1:20 handle 20: sfq perturb 10 $TC qdisc add dev $DEV parent 1:30 handle 30: sfq perturb 10 $TC filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip protocol 17 0xff flowid 1:10 Currently the filter puts all UDP traffic (through which the voice goes) to 1:10. The script works partially: when uploading from the LAN and starting a call, the upload rate decreases exactly as needed by the voice, BUT the voice has LARGE delays - up to 2 secs. Is there an option to put (for instance) all UDP traffic at the beginning of the output queue?
