hi,
the script that generated this error is basically
the below command:
set ns [new Simulator]
set n0 [$ns node]
set n1 [$ns node] set f [open out.tr w]
$ns trace-all $f # install a duplex link with WFQ queues at both ends $ns duplex-link $n0 $n1 5Mb 2ms WFQ # create an instance of the classifier suited for
flow aggregation
set cl [new WFQAggregClassifier] # install the classifier on the WFQ server at node
$n0 heading at nt $n1
$ns wfqclassifier-install $n0 $n1 $cl # in this example we have a flow for each queue
but
# more than one flow can be assigned to the same WFQ server queue(PGPS session) $cl setqueue 0 3; # fid 0 -> WFQ server queue 3 $cl setqueue 1 4; # fid 1 -> WFQ server queue 4 #we set WFQ server queue weights
$cl setweight 3 .5; # WFQ server queue 3 has weight .5 $cl setlength 3 13; # WFQ server queue 3 has length 13 packets $cl setweight 4 .2; # WFQ server queue 5 has weight .2 $cl setlength 4 20; # WFQ server queue 5 has length 20 packets ................
$ns at 1.0 "$cbr0 start"
$ns at 1.1 "$cbr1 start" $ns at 3.0 "finish"
