no, i haven't do a test on OSPF network yet. and recently i am busy , and i'm sure whether i can find some time to do this in the recent weeks :( i attached my qdisc_cfg file. i first run $iptables -A OUTPUT -t mangle -j FTOS --set-ftos 0xfc this will mark the packet origined from the local machine be marked with a dscp=0x3f, which in my qdisc_cfg file has the highest priority. then , i run $qdisc_cfg core which will first setup a prio qdisc with 5 bands, band 4 is used for the packets with a dscp=0, and band 2 is used for the packets with some none zero dscp value band 0, band 1 and band 3 are currently not used. i can say that after i do the following two steps , the packets from local stack is always have a dscp value 0x3f, which will be send out first. of course the traffic generated by the tcpblast is marked with a zero dscp value. i also noticed that, no matter i use qdisc_cfg or not, the results are the same -- the ldp stopped after about 10 to 15 seconds of the congestion. :( folke. >From: "James R.
