hi I wanted to set the properties of some queuing algos eg. DRR so what I did was this : set d [new Queue/DRR] {here set properties} $ns duplex-link $n0 $n2 1Mb 10ms $d the above line does not compile. i.e. gives an error. Can you tell me where the error lies. Or am I doing something completely absurd? --sudhir
